 f. Updated Service Console package python

  Service Console package Python update to version 2.4.3-24.el5.

  When the assert() system call was disabled, an input sanitization   flaw was revealed in the Python string object implementation that   led to a buffer overflow. The missing check for negative size values   meant the Python memory allocator could allocate less memory than   expected. This could result in arbitrary code execution with the   Python interpreter's privileges.

  Multiple buffer and integer overflow flaws were found in the Python   Unicode string processing and in the Python Unicode and string   object implementations. An attacker could use these flaws to cause   a denial of service.

  Multiple integer overflow flaws were found in the Python imageop   module. If a Python application used the imageop module to   process untrusted images, it could cause the application to   disclose sensitive information, crash or, potentially, execute   arbitrary code with the Python interpreter's privileges.

  Multiple integer underflow and overflow flaws were found in the   Python snprintf() wrapper implementation. An attacker could use   these flaws to cause a denial of service (memory corruption).

  Multiple integer overflow flaws were found in various Python   modules. An attacker could use these flaws to cause a denial of   service.

  An integer signedness error, leading to a buffer overflow, was   found in the Python zlib extension module. If a Python application   requested the negative byte count be flushed for a decompression   stream, it could cause the application to crash or, potentially,   execute arbitrary code with the Python interpreter's privileges.

  A flaw was discovered in the strxfrm() function of the Python   locale module. Strings generated by this function were not properly   NULL-terminated, which could possibly cause disclosure of data   stored in the memory of a Python application using this function.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2007-2052 CVE-2007-4965 CVE-2008-1721   CVE-2008-1887 CVE-2008-2315 CVE-2008-3142 CVE-2008-3143   CVE-2008-3144 CVE-2008-4864 CVE-2008-5031 to these issues.

 g. Updated Service Console package bind

  Service Console package bind updated to version 9.3.6-4.P1.el5

  The Berkeley Internet Name Domain (BIND) is an implementation of the   Domain Name System (DNS) protocols. BIND includes a DNS server   (named); a resolver library (routines for applications to use when   interfacing with DNS); and tools for verifying that the DNS server   is operating correctly.

  A flaw was found in the way BIND handles dynamic update message   packets containing the 'ANY' record type. A remote attacker could   use this flaw to send a specially crafted dynamic update packet   that could cause named to exit with an assertion failure.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-0696 to this issue.

 h. Updated Service Console package libxml2

  Service Console package libxml2 updated to version 2.6.26-2.1.2.8.

  libxml is a library for parsing and manipulating XML files. A   Document Type Definition (DTD) defines the legal syntax (and also   which elements can be used) for certain types of files, such as XML   files.

  A stack overflow flaw was found in the way libxml processes the   root XML document element definition in a DTD. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  Multiple use-after-free flaws were found in the way libxml parses   the Notation and Enumeration attribute types. A remote attacker   could provide a specially crafted XML file, which once opened by a   local, unsuspecting user, would lead to denial of service.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the names CVE-2009-2414 and CVE-2009-2416 to these   issues.

 i. Updated Service Console package curl

  Service Console package curl updated to version 7.15.5-2.1.el5_3.5

  A cURL is affected by the previously published 'null prefix attack',   caused by incorrect handling of NULL characters in X.509   certificates. If an attacker is able to get a carefully-crafted   certificate signed by a trusted Certificate Authority, the attacker   could use the certificate during a man-in-the-middle attack and   potentially confuse cURL into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2417 to this issue

 j. Updated Service Console package gnutls

  Service Console package gnutil updated to version 1.4.1-3.el5_3.5

  A flaw was discovered in the way GnuTLS handles NULL characters in   certain fields of X.509 certificates. If an attacker is able to get   a carefully-crafted certificate signed by a Certificate Authority   trusted by an application using GnuTLS, the attacker could use the   certificate during a man-in-the-middle attack and potentially   confuse the application into accepting it by mistake.

  The Common Vulnerabilities and Exposures project (cve.mitre.org)   has assigned the name CVE-2009-2730 to this issue

The remote MiracleLinux 3 host has packages installed that are affected by multiple vulnerabilities as referenced in the AXSA:2009-396:11 advisory.

    The kernel package contains the Linux kernel (vmlinuz), the core of any Linux operating system.  The     kernel handles the basic functions of the operating system:  memory allocation, process allocation, device     input and output, etc.
    Fixed bugs:
    CVE-2009-2847     The do_sigaltstack function in kernel/signal.c in Linux kernel 2.4 through 2.4.37 and 2.6 before     2.6.31-rc5, when running on 64-bit systems, does not clear certain padding bytes from a structure, which     allows local users to obtain sensitive information from the kernel stack via the sigaltstack function.
    CVE-2009-2848     The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the     current->clear_child_tid pointer, which allows local users to cause a denial of service (memory     corruption) via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not     properly handled during thread creation and exit.

Tenable has extracted the preceding description block directly from the MiracleLinux security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Updated kernel packages that fix security issues, address several hundred bugs and add numerous enhancements are now available as part of the ongoing support and maintenance of Red Hat Enterprise Linux version 5. This is the fourth regular update.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

These updated packages fix the following security issues :

* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)

* a flaw was found in the way the do_sigaltstack() function in the Linux kernel copies the stack_t structure to user-space. On 64-bit machines, this flaw could lead to a four-byte information leak.
(CVE-2009-2847, Moderate)

* a flaw was found in the ext4 file system code. A local attacker could use this flaw to cause a denial of service by performing a resize operation on a specially crafted ext4 file system.
(CVE-2009-0745, Low)

* multiple flaws were found in the ext4 file system code. A local attacker could use these flaws to cause a denial of service by mounting a specially crafted ext4 file system. (CVE-2009-0746, CVE-2009-0747, CVE-2009-0748, Low)

These updated packages also include several hundred bug fixes for and enhancements to the Linux kernel. Space precludes documenting each of these changes in this advisory and users are directed to the Red Hat Enterprise Linux 5.4 Release Notes for information on the most significant of these changes :

http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/ Release_Notes/

Also, for details concerning every bug fixed in and every enhancement added to the kernel for this release, see the kernel chapter in the Red Hat Enterprise Linux 5.4 Technical Notes :

http://www.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/5.4/html/ Technical_Notes/kernel.html

All Red Hat Enterprise Linux 5 users are advised to install these updated packages, which address these vulnerabilities as well as fixing the bugs and adding the enhancements noted in the Red Hat Enterprise Linux 5.4 Release Notes and Technical Notes. The system must be rebooted for this update to take effect.

This update fixes various security issues and some bugs in the SUSE Linux Enterprise 9 kernel.

The following security bugs were fixed :

  - A race condition in the pipe(2) systemcall could be used     by local attackers to execute code. (CVE-2009-3547)

  - On x86_64 systems a information leak of high register     contents (upper 32bit) was fixed. (CVE-2009-2910)

  - The (1) agp_generic_alloc_page and (2)     agp_generic_alloc_pages functions in     drivers/char/agp/generic.c in the agp subsystem in the     Linux kernel do not zero out pages that may later be     available to a user-space process, which allows local     users to obtain sensitive information by reading these     pages. (CVE-2009-1192)

  - Unsigned check in the ax25 socket handler could allow     local attackers to potentially crash the kernel or even     execute code. (CVE-2009-2909)

  - The execve function in the Linux kernel did not properly     clear the current->clear_child_tid pointer, which allows     local users to cause a denial of service (memory     corruption) or possibly gain privileges via a clone     system call with CLONE_CHILD_SETTID or     CLONE_CHILD_CLEARTID enabled, which is not properly     handled during thread creation and exit. (CVE-2009-2848)

  - Fixed various sockethandler getname leaks, which could     disclose memory previously used by the kernel or other     userland processes to the local attacker.
    (CVE-2009-3002)

  - Multiple buffer overflows in the cifs subsystem in the     Linux kernel allow remote CIFS servers to cause a denial     of service (memory corruption) and possibly have     unspecified other impact via (1) a malformed Unicode     string, related to Unicode string area alignment in     fs/cifs/sess.c; or (2) long Unicode characters, related     to fs/cifs/cifssmb.c and the cifs_readdir function in     fs/cifs/readdir.c. (CVE-2009-1633)

  - The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the     NFSv4 client in the allows remote NFS servers to cause a     denial of service (NULL pointer dereference and panic)     by sending a certain response containing incorrect file     attributes, which trigger attempted use of an open file     that lacks NFSv4 state. (CVE-2009-3726)

Updated kernel packages that fix several security issues and multiple bugs are now available for Red Hat Enterprise Linux 3.

This update has been rated as having important security impact by the Red Hat Security Response Team.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

Security fixes :

* when fput() was called to close a socket, the __scm_destroy() function in the Linux kernel could make indirect recursive calls to itself. This could, potentially, lead to a denial of service issue.
(CVE-2008-5029, Important)

* the sendmsg() function in the Linux kernel did not block during UNIX socket garbage collection. This could, potentially, lead to a local denial of service. (CVE-2008-5300, Important)

* the exit_notify() function in the Linux kernel did not properly reset the exit signal if a process executed a set user ID (setuid) application before exiting. This could allow a local, unprivileged user to elevate their privileges. (CVE-2009-1337, Important)

* a flaw was found in the Intel PRO/1000 network driver in the Linux kernel. Frames with sizes near the MTU of an interface may be split across multiple hardware receive descriptors. Receipt of such a frame could leak through a validation check, leading to a corruption of the length check. A remote attacker could use this flaw to send a specially crafted packet that would cause a denial of service or code execution. (CVE-2009-1385, Important)

* the ADDR_COMPAT_LAYOUT and MMAP_PAGE_ZERO flags were not cleared when a setuid or setgid program was executed. A local, unprivileged user could use this flaw to bypass the mmap_min_addr protection mechanism and perform a NULL pointer dereference attack, or bypass the Address Space Layout Randomization (ASLR) security feature.
(CVE-2009-1895, Important)

* it was discovered that, when executing a new process, the clear_child_tid pointer in the Linux kernel is not cleared. If this pointer points to a writable portion of the memory of the new program, the kernel could corrupt four bytes of memory, possibly leading to a local denial of service or privilege escalation. (CVE-2009-2848, Important)

* missing initialization flaws were found in getname() implementations in the IrDA sockets, AppleTalk DDP protocol, NET/ROM protocol, and ROSE protocol implementations in the Linux kernel. Certain data structures in these getname() implementations were not initialized properly before being copied to user-space. These flaws could lead to an information leak. (CVE-2009-3002, Important)

* a NULL pointer dereference flaw was found in each of the following functions in the Linux kernel: pipe_read_open(), pipe_write_open(), and pipe_rdwr_open(). When the mutex lock is not held, the i_pipe pointer could be released by other processes before it is used to update the pipe's reader and writer counters. This could lead to a local denial of service or privilege escalation. (CVE-2009-3547, Important)

Bug fixes :

* this update adds the mmap_min_addr tunable and restriction checks to help prevent unprivileged users from creating new memory mappings below the minimum address. This can help prevent the exploitation of NULL pointer dereference bugs. Note that mmap_min_addr is set to zero (disabled) by default for backwards compatibility. (BZ#512642)

* a bridge reference count problem in IPv6 has been fixed. (BZ#457010)

* enforce null-termination of user-supplied arguments to setsockopt().
(BZ#505514)

* the gcc flag '-fno-delete-null-pointer-checks' was added to the kernel build options. This prevents gcc from optimizing out NULL pointer checks after the first use of a pointer. NULL pointer bugs are often exploited by attackers. Keeping these checks is a safety measure. (BZ#511185)

* a check has been added to the IPv4 code to make sure that rt is not NULL, to help prevent future bugs in functions that call ip_append_data() from being exploitable. (BZ#520300)

Users should upgrade to these updated packages, which contain backported patches to correct these issues. The system must be rebooted for this update to take effect.

The remote OracleVM system is missing necessary patches to address critical security updates : please see Oracle VM Security Advisory OVMSA-2013-0039 for details.

Security fixes: - CVE-2009-2691: Information disclosure in proc filesystem - CVE-2009-2848: execve: must clear current->child_tid - CVE-2009-2849: md: NULL pointer dereference - CVE-2009-2847:
Information leak in do_sigaltstack Restore missing LIRC drivers, dropped in previous release. Backport upstream fixes that further improve the security of mmap of low addresses. (CVE-2009-2695)

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Several vulnerabilities have been discovered in the Linux kernel that may lead to denial of service, privilege escalation or a leak of sensitive memory. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-2698     Herbert Xu discovered an issue in the way UDP tracks     corking status that could allow local users to cause a     denial of service (system crash). Tavis Ormandy and     Julien Tinnes discovered that this issue could also be     used by local users to gain elevated privileges.

  - CVE-2009-2846     Michael Buesch noticed a typing issue in the eisa-eeprom     driver for the hppa architecture. Local users could     exploit this issue to gain access to restricted memory.

  - CVE-2009-2847     Ulrich Drepper noticed an issue in the do_sigalstack     routine on 64-bit systems. This issue allows local users     to gain access to potentially sensitive memory on the     kernel stack.

  - CVE-2009-2848     Eric Dumazet discovered an issue in the execve path,     where the clear_child_tid variable was not being     properly cleared. Local users could exploit this issue     to cause a denial of service (memory corruption).

  - CVE-2009-2849     Neil Brown discovered an issue in the sysfs interface to     md devices. When md arrays are not active, local users     can exploit this vulnerability to cause a denial of     service (oops).

This update fixes a several security issues and various bugs in the SUSE Linux Enterprise 10 SP 2 kernel.

The following security issues were fixed: CVE-2009-3547: A race condition during pipe open could be used by local attackers to elevate privileges.

  - On x86_64 systems a information leak of high register     contents (upper 32bit) was fixed. (CVE-2009-2910)

  - The randomness of the ASLR methods used in the kernel     was increased. (CVE-2009-3238)

  - A information leak from the kernel due to uninitialized     memory in AGP handling was fixed. (CVE-2009-1192)

  - A signed comparison in the ax25 sockopt handler was     fixed which could be used to crash the kernel or     potentially execute code. (CVE-2009-2909)

  - The execve function in the Linux kernel did not properly     clear the current->clear_child_tid pointer, which allows     local users to cause a denial of service (memory     corruption) or possibly gain privileges via a clone     system call with CLONE_CHILD_SETTID or     CLONE_CHILD_CLEARTID enabled, which is not properly     handled during thread creation and exit. (CVE-2009-2848)

  - Fixed various sockethandler getname leaks, which could     disclose memory previously used by the kernel or other     userland processes to the local attacker.
    (CVE-2009-3002)

  - Multiple buffer overflows in the cifs subsystem in the     Linux kernel allow remote CIFS servers to cause a denial     of service (memory corruption) and possibly have     unspecified other impact via (1) a malformed Unicode     string, related to Unicode string area alignment in     fs/cifs/sess.c; or (2) long Unicode characters, related     to fs/cifs/cifssmb.c and the cifs_readdir function in     fs/cifs/readdir.c. (CVE-2009-1633)

Also see the RPM changelog for more changes.

This kernel update for openSUSE 11.0 fixes some bugs and several security problems.

The following security issues are fixed: CVE-2009-4536:
drivers/net/e1000/e1000_main.c in the e1000 driver in the Linux kernel handles Ethernet frames that exceed the MTU by processing certain trailing payload data as if it were a complete frame, which allows remote attackers to bypass packet filters via a large packet with a crafted payload.

CVE-2009-4538: drivers/net/e1000e/netdev.c in the e1000e driver in the Linux kernel does not properly check the size of an Ethernet frame that exceeds the MTU, which allows remote attackers to have an unspecified impact via crafted packets.

CVE-2010-0007: Missing CAP_NET_ADMIN checks in the ebtables netfilter code might have allowed local attackers to modify bridge firewall settings.

CVE-2010-0003: An information leakage on fatal signals on x86_64 machines was fixed.

CVE-2009-4138: drivers/firewire/ohci.c in the Linux kernel, when packet-per-buffer mode is used, allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly have unknown other impact via an unspecified ioctl associated with receiving an ISO packet that contains zero in the payload-length field.

CVE-2009-4308: The ext4_decode_error function in fs/ext4/super.c in the ext4 filesystem in the Linux kernel before 2.6.32 allows user-assisted remote attackers to cause a denial of service (NULL pointer dereference), and possibly have unspecified other impact, via a crafted read-only filesystem that lacks a journal.

CVE-2009-3939: The poll_mode_io file for the megaraid_sas driver in the Linux kernel 2.6.31.6 and earlier has world-writable permissions, which allows local users to change the I/O mode of the driver by modifying this file.

CVE-2009-4021: The fuse_direct_io function in fs/fuse/file.c in the fuse subsystem in the Linux kernel before 2.6.32-rc7 might allow attackers to cause a denial of service (invalid pointer dereference and OOPS) via vectors possibly related to a memory-consumption attack.

CVE-2009-3547: A race condition in the pipe(2) systemcall could be used by local attackers to hang the machine. The kernel in Moblin 2.0 uses NULL ptr protection which avoids code execution possbilities.

CVE-2009-2903: Memory leak in the appletalk subsystem in the Linux kernel 2.4.x through 2.4.37.6 and 2.6.x through 2.6.31, when the appletalk and ipddp modules are loaded but the ipddp'N' device is not found, allows remote attackers to cause a denial of service (memory consumption) via IP-DDP datagrams.

CVE-2009-3621: net/unix/af_unix.c in the Linux kernel 2.6.31.4 and earlier allows local users to cause a denial of service (system hang) by creating an abstract-namespace AF_UNIX listening socket, performing a shutdown operation on this socket, and then performing a series of connect operations to this socket.

CVE-2009-3612: The tcf_fill_node function in net/sched/cls_api.c in the netlink subsystem in the Linux kernel 2.6.x before 2.6.32-rc5, and 2.4.37.6 and earlier, does not initialize a certain tcm__pad2 structure member, which might allow local users to obtain sensitive information from kernel memory via unspecified vectors.

CVE-2009-3620: The ATI Rage 128 (aka r128) driver in the Linux kernel before 2.6.31-git11 does not properly verify Concurrent Command Engine (CCE) state initialization, which allows local users to cause a denial of service (NULL pointer dereference and system crash) or possibly gain privileges via unspecified ioctl calls.

CVE-2009-3726: The nfs4_proc_lock function in fs/nfs/nfs4proc.c in the NFSv4 client in the Linux kernel before 2.6.31-rc4 allows remote NFS servers to cause a denial of service (NULL pointer dereference and panic) by sending a certain response containing incorrect file attributes, which trigger attempted use of an open file that lacks NFSv4 state.

CVE-2009-3286: NFSv4 in the Linux kernel 2.6.18, and possibly other versions, does not properly clean up an inode when an O_EXCL create fails, which causes files to be created with insecure settings such as setuid bits, and possibly allows local users to gain privileges, related to the execution of the do_open_permission function even when a create fails.

CVE-2009-2910: arch/x86/ia32/ia32entry.S in the Linux kernel before 2.6.31.4 on the x86_64 platform does not clear certain kernel registers before a return to user mode, which allows local users to read register values from an earlier process by switching an ia32 process to 64-bit mode.

CVE-2009-3238: The get_random_int function in drivers/char/random.c in the Linux kernel before 2.6.30 produces insufficiently random numbers, which allows attackers to predict the return value, and possibly defeat protection mechanisms based on randomization, via vectors that leverage the function's tendency to 'return the same value over and over again for long stretches of time.'

CVE-2009-2848: The execve function in the Linux kernel, possibly 2.6.30-rc6 and earlier, does not properly clear the current->clear_child_tid pointer, which allows local users to cause a denial of service (memory corruption) or possibly gain privileges via a clone system call with CLONE_CHILD_SETTID or CLONE_CHILD_CLEARTID enabled, which is not properly handled during thread creation and exit.

CVE-2009-3002: The Linux kernel before 2.6.31-rc7 does not initialize certain data structures within getname functions, which allows local users to read the contents of some kernel memory locations by calling getsockname on (1) an AF_APPLETALK socket, related to the atalk_getname function in net/appletalk/ddp.c; (2) an AF_IRDA socket, related to the irda_getname function in net/irda/af_irda.c; (3) an AF_ECONET socket, related to the econet_getname function in net/econet/af_econet.c; (4) an AF_NETROM socket, related to the nr_getname function in net/netrom/af_netrom.c; (5) an AF_ROSE socket, related to the rose_getname function in net/rose/af_rose.c; or (6) a raw CAN socket, related to the raw_getname function in net/can/raw.c.

CVE-2009-1633: Multiple buffer overflows in the cifs subsystem in the Linux kernel before 2.6.29.4 allow remote CIFS servers to cause a denial of service (memory corruption) and possibly have unspecified other impact via (1) a malformed Unicode string, related to Unicode string area alignment in fs/cifs/sess.c; or (2) long Unicode characters, related to fs/cifs/cifssmb.c and the cifs_readdir function in fs/cifs/readdir.c.

Several vulnerabilities have been discovered in the Linux kernel that may lead to a denial of service, sensitive memory leak or privilege escalation. The Common Vulnerabilities and Exposures project identifies the following problems :

  - CVE-2009-2846     Michael Buesch noticed a typing issue in the eisa-eeprom     driver for the hppa architecture. Local users could     exploit this issue to gain access to restricted memory.

  - CVE-2009-2847     Ulrich Drepper noticed an issue in the do_sigalstack     routine on 64-bit systems. This issue allows local users     to gain access to potentially sensitive memory on the     kernel stack.

  - CVE-2009-2848     Eric Dumazet discovered an issue in the execve path,     where the clear_child_tid variable was not being     properly cleared. Local users could exploit this issue     to cause a denial of service (memory corruption).

  - CVE-2009-2849     Neil Brown discovered an issue in the sysfs interface to     md devices. When md arrays are not active, local users     can exploit this vulnerability to cause a denial of     service (oops).

  - CVE-2009-2903     Mark Smith discovered a memory leak in the appletalk     implementation. When the appletalk and ipddp modules are     loaded, but no ipddp'N' device is found, remote     attackers can cause a denial of service by consuming     large amounts of system memory.

  - CVE-2009-2908     Loic Minier discovered an issue in the eCryptfs     filesystem. A local user can cause a denial of service     (kernel oops) by causing a dentry value to go negative.

  - CVE-2009-2909     Arjan van de Ven discovered an issue in the AX.25     protocol implementation. A specially crafted call to     setsockopt() can result in a denial of service (kernel     oops).

  - CVE-2009-2910     Jan Beulich discovered the existence of a sensitive     kernel memory leak. Systems running the 'amd64' kernel     do not properly sanitize registers for 32-bit processes.

  - CVE-2009-3001     Jiri Slaby fixed a sensitive memory leak issue in the     ANSI/IEEE 802.2 LLC implementation. This is not     exploitable in the Debian lenny kernel as root     privileges are required to exploit this issue.

  - CVE-2009-3002     Eric Dumazet fixed several sensitive memory leaks in the     IrDA, X.25 PLP (Rose), NET/ROM, Acorn Econet/AUN, and     Controller Area Network (CAN) implementations. Local     users can exploit these issues to gain access to kernel     memory.

  - CVE-2009-3228     Eric Dumazet reported an instance of uninitialized     kernel memory in the network packet scheduler. Local     users may be able to exploit this issue to read the     contents of sensitive kernel memory.

  - CVE-2009-3238     Linus Torvalds provided a change to the get_random_int()     function to increase its randomness.

  - CVE-2009-3286     Eric Paris discovered an issue with the NFSv4 server     implementation. When an O_EXCL create fails, files may     be left with corrupted permissions, possibly granting     unintentional privileges to other local users.

  - CVE-2009-3547     Earl Chew discovered a NULL pointer dereference issue in     the pipe_rdwr_open function which can be used by local     users to gain elevated privileges.

  - CVE-2009-3612     Jiri Pirko discovered a typo in the initialization of a     structure in the netlink subsystem that may allow local     users to gain access to sensitive kernel memory.

  - CVE-2009-3613     Alistair Strachan reported an issue in the r8169 driver.
    Remote users can cause a denial of service (IOMMU space     exhaustion and system crash) by transmitting a large     amount of jumbo frames.

  - CVE-2009-3620     Ben Hutchings discovered an issue in the DRM manager for     ATI Rage 128 graphics adapters. Local users may be able     to exploit this vulnerability to cause a denial of     service (NULL pointer dereference).

  - CVE-2009-3621     Tomoki Sekiyama discovered a deadlock condition in the     UNIX domain socket implementation. Local users can     exploit this vulnerability to cause a denial of service     (system hang).
