The openSUSE 11.3 kernel was updated to 2.6.34.10 to fix various bugs and security issues.

Following security issues have been fixed: CVE-2011-2495: The /proc/PID/io interface could be used by local attackers to gain information on other processes like number of password characters typed or similar.

CVE-2011-2484: The add_del_listener function in kernel/taskstats.c in the Linux kernel did not prevent multiple registrations of exit handlers, which allowed local users to cause a denial of service (memory and CPU consumption), and bypass the OOM Killer, via a crafted application.

CVE-2011-2491: A local unprivileged user able to access a NFS filesystem could use file locking to deadlock parts of an nfs server under some circumstance.

CVE-2011-2496: The normal mmap paths all avoid creating a mapping where the pgoff inside the mapping could wrap around due to overflow.
However, an expanding mremap() can take such a non-wrapping mapping and make it bigger and cause a wrapping condition.

CVE-2011-1017,CVE-2011-2182: The code for evaluating LDM partitions (in fs/partitions/ldm.c) contained bugs that could crash the kernel for certain corrupted LDM partitions.

CVE-2011-1479: A regression in inotify fix for a memory leak could lead to a double free corruption which could crash the system.

CVE-2011-1593: Multiple integer overflows in the next_pidmap function in kernel/pid.c in the Linux kernel allowed local users to cause a denial of service (system crash) via a crafted (1) getdents or (2) readdir system call.

CVE-2011-1020: The proc filesystem implementation in the Linux kernel did not restrict access to the /proc directory tree of a process after this process performs an exec of a setuid program, which allowed local users to obtain sensitive information or cause a denial of service via open, lseek, read, and write system calls.

CVE-2011-1585: When using a setuid root mount.cifs, local users could hijack password protected mounted CIFS shares of other local users.

CVE-2011-1160: Kernel information via the TPM devices could by used by local attackers to read kernel memory.

CVE-2011-1577: The Linux kernel automatically evaluated partition tables of storage devices. The code for evaluating EFI GUID partitions (in fs/partitions/efi.c) contained a bug that causes a kernel oops on certain corrupted GUID partition tables, which might be used by local attackers to crash the kernel or potentially execute code.

CVE-2011-1180: In the IrDA module, length fields provided by a peer for names and attributes may be longer than the destination array sizes and were not checked, this allowed local attackers (close to the irda port) to potentially corrupt memory.

CVE-2011-1016: The Radeon GPU drivers in the Linux kernel did not properly validate data related to the AA resolve registers, which allowed local users to write to arbitrary memory locations associated with (1) Video RAM (aka VRAM) or (2) the Graphics Translation Table (GTT) via crafted values.

CVE-2011-1013: A signedness issue in the drm ioctl handling could be used by local attackers to potentially overflow kernel buffers and execute code.

This update also includes changes queued for the next point release of Debian 6.0, which also fix various non-security issues. These additional changes are described in the package changelog.

The SUSE Linux Enterprise 11 Service Pack 1 kernel was updated to 2.6.32.43 and fixes various bugs and security issues.

The following security issues were fixed :

  - The normal mmap paths all avoid creating a mapping where     the pgoff inside the mapping could wrap around due to     overflow. However, an expanding mremap() can take such a     non-wrapping mapping and make it bigger and cause a     wrapping condition. (CVE-2011-2496)

  - A local unprivileged user able to access a NFS     filesystem could use file locking to deadlock parts of     an nfs server under some circumstance. (CVE-2011-2491)

  - Fixed a race between ksmd and other memory management     code, which could result in a NULL ptr dereference and     kernel crash. (CVE-2011-2183)

  - In both trigger_scan and sched_scan operations, we were     checking for the SSID length before assigning the value     correctly. Since the memory was just kzalloced, the     check was always failing and SSID with over 32     characters were allowed to go through. This required     CAP_NET_ADMIN privileges to be exploited.
    (CVE-2011-2517)

  - A malicious user or buggy application could inject     diagnosing byte code and trigger an infinite loop in     inet_diag_bc_audit(). (CVE-2011-2213)

  - The code for evaluating LDM partitions (in     fs/partitions/ldm.c) contained bugs that could crash the     kernel for certain corrupted LDM partitions.
    (CVE-2011-1017 / CVE-2011-1012 / CVE-2011-2182)

  - Multiple integer overflows in the next_pidmap function     in kernel/pid.c in the Linux kernel allowed local users     to cause a denial of service (system crash) via a     crafted (1) getdents or (2) readdir system call.
    (CVE-2011-1593)

  - The proc filesystem implementation in the Linux kernel     did not restrict access to the /proc directory tree of a     process after this process performs an exec of a setuid     program, which allowed local users to obtain sensitive     information or cause a denial of service via open,     lseek, read, and write system calls. (CVE-2011-1020)

  - When using a setuid root mount.cifs, local users could     hijack password protected mounted CIFS shares of other     local users. (CVE-2011-1585)

  - Kernel information via the TPM devices could by used by     local attackers to read kernel memory. (CVE-2011-1160)

  - The Linux kernel automatically evaluated partition     tables of storage devices. The code for evaluating EFI     GUID partitions (in fs/partitions/efi.c) contained a bug     that causes a kernel oops on certain corrupted GUID     partition tables, which might be used by local attackers     to crash the kernel or potentially execute code.
    (CVE-2011-1577)

  - In a bluetooth ioctl, struct sco_conninfo has one     padding byte in the end. Local variable cinfo of type     sco_conninfo was copied to userspace with this     uninizialized one byte, leading to an old stack contents     leak. (CVE-2011-1078)

  - In a bluetooth ioctl, struct ca is copied from     userspace. It was not checked whether the 'device' field     was NULL terminated. This potentially leads to BUG()     inside of alloc_netdev_mqs() and/or information leak by     creating a device with a name made of contents of kernel     stack. (CVE-2011-1079)

  - In ebtables rule loading, struct tmp is copied from     userspace. It was not checked whether the 'name' field     is NULL terminated. This may have lead to buffer     overflow and passing contents of kernel stack as a     module name to try_then_request_module() and,     consequently, to modprobe commandline. It would be seen     by all userspace processes. (CVE-2011-1080)

  - The econet_sendmsg function in net/econet/af_econet.c in     the Linux kernel on the x86_64 platform allowed remote     attackers to obtain potentially sensitive information     from kernel stack memory by reading uninitialized data     in the ah field of an Acorn Universal Networking (AUN)     packet. (CVE-2011-1173)

  - net/ipv4/netfilter/arp_tables.c in the IPv4     implementation in the Linux kernel did not place the     expected '0' character at the end of string data in the     values of certain structure members, which allowed local     users to obtain potentially sensitive information from     kernel memory by leveraging the CAP_NET_ADMIN capability     to issue a crafted request, and then reading the     argument to the resulting modprobe process.
    (CVE-2011-1170)

  - net/ipv4/netfilter/ip_tables.c in the IPv4     implementation in the Linux kernel did not place the     expected '0' character at the end of string data in the     values of certain structure members, which allowed local     users to obtain potentially sensitive information from     kernel memory by leveraging the CAP_NET_ADMIN capability     to issue a crafted request, and then reading the     argument to the resulting modprobe process.
    (CVE-2011-1171)

  - net/ipv6/netfilter/ip6_tables.c in the IPv6     implementation in the Linux kernel did not place the     expected '0' character at the end of string data in the     values of certain structure members, which allowed local     users to obtain potentially sensitive information from     kernel memory by leveraging the CAP_NET_ADMIN capability     to issue a crafted request, and then reading the     argument to the resulting modprobe process.
    (CVE-2011-1172)

  - Multiple integer overflows in the (1)     agp_allocate_memory and (2) agp_create_user_memory     functions in drivers/char/agp/generic.c in the Linux     kernel before allowed local users to trigger buffer     overflows, and consequently cause a denial of service     (system crash) or possibly have unspecified other     impact, via vectors related to calls that specify a     large number of memory pages. (CVE-2011-1746)

  - Integer overflow in the agp_generic_insert_memory     function in drivers/char/agp/generic.c in the Linux     kernel allowed local users to gain privileges or cause a     denial of service (system crash) via a crafted     AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745)

  - The bcm_release function in net/can/bcm.c in the Linux     kernel did not properly validate a socket data     structure, which allowed local users to cause a denial     of service (NULL pointer dereference) or possibly have     unspecified other impact via a crafted release     operation. (CVE-2011-1598)

  - The raw_release function in net/can/raw.c in the Linux     kernel did not properly validate a socket data     structure, which allows local users to cause a denial of     service (NULL pointer dereference) or possibly have     unspecified other impact via a crafted release     operation. (CVE-2011-1748)

    - [netdrv] be2net: Merge fixes for CVE-2011-3347 (Joe Jin)

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

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

This kernel update for the SUSE Linux Enterprise 10 SP4 kernel fixes several security issues and bugs.

The following security issues were fixed :

  - The dccp_rcv_state_process function in net/dccp/input.c     in the Datagram Congestion Control Protocol (DCCP)     implementation in the Linux kernel did not properly     handle packets for a CLOSED endpoint, which allowed     remote attackers to cause a denial of service (NULL     pointer dereference and OOPS) by sending a DCCP-Close     packet followed by a DCCP-Reset packet. (CVE-2011-1093)

  - The add_del_listener function in kernel/taskstats.c in     the Linux kernel did not prevent multiple registrations     of exit handlers, which allowed local users to cause a     denial of service (memory and CPU consumption), and     bypass the OOM Killer, via a crafted application.
    (CVE-2011-2484)

  - Integer overflow in the agp_generic_insert_memory     function in drivers/char/agp/generic.c in the Linux     kernel allowed local users to gain privileges or cause a     denial of service (system crash) via a crafted     AGPIOC_BIND agp_ioctl ioctl call. (CVE-2011-1745)

  - Multiple integer overflows in the (1)     agp_allocate_memory and (2) agp_create_user_memory     functions in drivers/char/agp/generic.c in the Linux     kernel allowed local users to trigger buffer overflows,     and consequently cause a denial of service (system     crash) or possibly have unspecified other impact, via     vectors related to calls that specify a large number of     memory pages. (CVE-2011-1746)

  - The agp_generic_remove_memory function in     drivers/char/agp/generic.c in the Linux kernel before     2.6.38.5 did not validate a certain start parameter,     which allowed local users to gain privileges or cause a     denial of service (system crash) via a crafted     AGPIOC_UNBIND agp_ioctl ioctl call, a different     vulnerability than CVE-2011-1745. (CVE-2011-2022)

  - When using a setuid root mount.cifs, local users could     hijack password protected mounted CIFS shares of other     local users. (CVE-2011-1585)

  - The do_task_stat function in fs/proc/array.c in the     Linux kernel did not perform an expected uid check,     which made it easier for local users to defeat the ASLR     protection mechanism by reading the start_code and     end_code fields in the /proc/#####/stat file for a     process executing a PIE binary. (CVE-2011-0726)

  - The normal mmap paths all avoid creating a mapping where     the pgoff inside the mapping could wrap around due to     overflow. However, an expanding mremap() can take such a     non-wrapping mapping and make it bigger and cause a     wrapping condition. (CVE-2011-2496)

  - A local unprivileged user able to access a NFS     filesystem could use file locking to deadlock parts of     an nfs server under some circumstance. (CVE-2011-2491)

  - The code for evaluating LDM partitions (in     fs/partitions/ldm.c) contained bugs that could crash the     kernel for certain corrupted LDM partitions.
    (CVE-2011-1017 / CVE-2011-2182)

  - Multiple integer overflows in the next_pidmap function     in kernel/pid.c in the Linux kernel allowed local users     to cause a denial of service (system crash) via a     crafted (1) getdents or (2) readdir system call.
    (CVE-2011-1593)

  - Integer overflow in the _ctl_do_mpt_command function in     drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel     might have allowed local users to gain privileges or     cause a denial of service (memory corruption) via an     ioctl call specifying a crafted value that triggers a     heap-based buffer overflow. (CVE-2011-1494)

  - drivers/scsi/mpt2sas/mpt2sas_ctl.c in the Linux kernel     did not validate (1) length and (2) offset values before     performing memory copy operations, which might have     allowed local users to gain privileges, cause a denial     of service (memory corruption), or obtain sensitive     information from kernel memory via a crafted ioctl call,     related to the _ctl_do_mpt_command and
    _ctl_diag_read_buffer functions. (CVE-2011-1495)
