This update fixes various security issues and several bugs in the openSUSE 11.0 kernel. It was also updated to the stable version 2.6.25.20.

CVE-2008-5702: Buffer underflow in the ibwdt_ioctl function in drivers/watchdog/ib700wdt.c might allow local users to have an unknown impact via a certain /dev/watchdog WDIOC_SETTIMEOUT IOCTL call.

CVE-2008-5700: libata did not set minimum timeouts for SG_IO requests, which allows local users to cause a denial of service (Programmed I/O mode on drives) via multiple simultaneous invocations of an unspecified test program.

CVE-2008-5079: net/atm/svc.c in the ATM subsystem allowed local users to cause a denial of service (kernel infinite loop) by making two calls to svc_listen for the same socket, and then reading a /proc/net/atm/*vc file, related to corruption of the vcc table.

CVE-2008-5300: Linux kernel 2.6.28 allows local users to cause a denial of service ('soft lockup' and process loss) via a large number of sendmsg function calls, which does not block during AF_UNIX garbage collection and triggers an OOM condition, a different vulnerability than CVE-2008-5029.

CVE-2008-5029: The __scm_destroy function in net/core/scm.c makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors.

CVE-2008-4933: Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function.

CVE-2008-5025: Stack-based buffer overflow in the hfs_cat_find_brec function in fs/hfs/catalog.c allowed attackers to cause a denial of service (memory corruption or system crash) via an hfs filesystem image with an invalid catalog namelength field, a related issue to CVE-2008-4933.

CVE-2008-5182: The inotify functionality might allow local users to gain privileges via unknown vectors related to race conditions in inotify watch removal and umount.

CVE-2008-3831: The i915 driver in drivers/char/drm/i915_dma.c does not restrict the DRM_I915_HWS_ADDR ioctl to the Direct Rendering Manager (DRM) master, which allows local users to cause a denial of service (memory corruption) via a crafted ioctl call, related to absence of the DRM_MASTER and DRM_ROOT_ONLY flags in the ioctl's configuration.

CVE-2008-4554: The do_splice_from function in fs/splice.c did not reject file descriptors that have the O_APPEND flag set, which allows local users to bypass append mode and make arbitrary changes to other locations in the file.

The SUSE Linux Enterprise 10 Service Pack 2 kernel was updated to fix some security issues and various bugs.

The following security problems have been fixed :

  - net/atm/svc.c in the ATM subsystem allowed local users     to cause a denial of service (kernel infinite loop) by     making two calls to svc_listen for the same socket, and     then reading a /proc/net/atm/ *vc file, related to     corruption of the vcc table. (CVE-2008-5079)

  - The __scm_destroy function in net/core/scm.c makes     indirect recursive calls to itself through calls to the     fput function, which allows local users to cause a     denial of service (panic) via vectors related to sending     an SCM_RIGHTS message through a UNIX domain socket and     closing file descriptors. (CVE-2008-5029)

  - Buffer overflow in the hfsplus_find_cat function in     fs/hfsplus/catalog.c allowed attackers to cause a denial     of service (memory corruption or system crash) via an     hfsplus filesystem image with an invalid catalog     namelength field, related to the     hfsplus_cat_build_key_uni function. (CVE-2008-4933)

  - Stack-based buffer overflow in the hfs_cat_find_brec     function in fs/hfs/catalog.c allowed attackers to cause     a denial of service (memory corruption or system crash)     via an hfs filesystem image with an invalid catalog     namelength field, a related issue to CVE-2008-4933.
    (CVE-2008-5025)

  - The inotify functionality might allow local users to     gain privileges via unknown vectors related to race     conditions in inotify watch removal and umount.
    (CVE-2008-5182)

A lot of other bugs were fixed, a detailed list can be found in the RPM changelog.

From Red Hat Security Advisory 2009:0014 :

Updated kernel packages that resolve several security issues and fix various bugs are now available for Red Hat Enterprise Linux 4.

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.

This update addresses the following security issues :

* 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)

* 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 local denial of service.
(CVE-2008-5029, Important)

* a deficiency was found in the Linux kernel virtual file system (VFS) implementation. This could allow a local, unprivileged user to make a series of file creations within deleted directories, possibly causing a denial of service. (CVE-2008-3275, Moderate)

* a buffer underflow flaw was found in the Linux kernel IB700 SBC watchdog timer driver. This deficiency could lead to a possible information leak. By default, the '/dev/watchdog' device is accessible only to the root user. (CVE-2008-5702, Low)

* the hfs and hfsplus file systems code failed to properly handle corrupted data structures. This could, potentially, lead to a local denial of service. (CVE-2008-4933, CVE-2008-5025, Low)

* a flaw was found in the hfsplus file system implementation. This could, potentially, lead to a local denial of service when write operations were performed. (CVE-2008-4934, Low)

This update also fixes the following bugs :

* when running Red Hat Enterprise Linux 4.6 and 4.7 on some systems running Intel(r) CPUs, the cpuspeed daemon did not run, preventing the CPU speed from being changed, such as not being reduced to an idle state when not in use.

* mmap() could be used to gain access to beyond the first megabyte of RAM, due to insufficient checks in the Linux kernel code. Checks have been added to prevent this.

* attempting to turn keyboard LEDs on and off rapidly on keyboards with slow keyboard controllers, may have caused key presses to fail.

* after migrating a hypervisor guest, the MAC address table was not updated, causing packet loss and preventing network connections to the guest. Now, a gratuitous ARP request is sent after migration. This refreshes the ARP caches, minimizing network downtime.

* writing crash dumps with diskdump may have caused a kernel panic on Non-Uniform Memory Access (NUMA) systems with certain memory configurations.

* on big-endian systems, such as PowerPC, the getsockopt() function incorrectly returned 0 depending on the parameters passed to it when the time to live (TTL) value equaled 255, possibly causing memory corruption and application crashes.

* a problem in the kernel packages provided by the RHSA-2008:0508 advisory caused the Linux kernel's built-in memory copy procedure to return the wrong error code after recovering from a page fault on AMD64 and Intel 64 systems. This may have caused other Linux kernel functions to return wrong error codes.

* a divide-by-zero bug in the Linux kernel process scheduler, which may have caused kernel panics on certain systems, has been resolved.

* the netconsole kernel module caused the Linux kernel to hang when slave interfaces of bonded network interfaces were started, resulting in a system hang or kernel panic when restarting the network.

* the '/proc/xen/' directory existed even if systems were not running Red Hat Virtualization. This may have caused problems for third-party software that checks virtualization-ability based on the existence of '/proc/xen/'. Note: this update will remove the '/proc/xen/' directory on systems not running Red Hat Virtualization.

All Red Hat Enterprise Linux 4 users should upgrade to these updated packages, which contain backported patches to resolve these issues.

Some vulnerabilities were discovered and corrected in the Linux 2.6 kernel :

Buffer overflow in the hfsplus_find_cat function in fs/hfsplus/catalog.c in the Linux kernel before 2.6.28-rc1 allows attackers to cause a denial of service (memory corruption or system crash) via an hfsplus filesystem image with an invalid catalog namelength field, related to the hfsplus_cat_build_key_uni function.
(CVE-2008-4933)

The hfsplus_block_allocate function in fs/hfsplus/bitmap.c in the Linux kernel before 2.6.28-rc1 does not check a certain return value from the read_mapping_page function before calling kmap, which allows attackers to cause a denial of service (system crash) via a crafted hfsplus filesystem image. (CVE-2008-4934)

The __scm_destroy function in net/core/scm.c in the Linux kernel 2.6.27.4, 2.6.26, and earlier makes indirect recursive calls to itself through calls to the fput function, which allows local users to cause a denial of service (panic) via vectors related to sending an SCM_RIGHTS message through a UNIX domain socket and closing file descriptors. (CVE-2008-5029)

Additionaly, support for a broadcom bluetooth dongle was added to btusb driver, an eeepc shutdown hang caused by snd-hda-intel was fixed, a Realtek auto-mute bug was fixed, the pcspkr driver was reenabled, an acpi brightness setting issue on some laptops was fixed, sata_nv (NVidia) driver bugs were fixed, horizontal mousewheel scrolling with Logitech V150 mouse was fixed, and more. Check the changelog and related bugs for more details.

This kernel also fixes the driver for Intel G45/GM45 video chipsets, in a way requiring also an updated Xorg driver, which is also being provided in this update.

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.

Updated kernel packages that resolve several security issues are now available for Red Hat Enterprise Linux 5.2 Extended Update Support.

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.

This update includes backported fixes for four security issues. These issues only affected users of Red Hat Enterprise Linux 5.2 Extended Update Support as they have already been addressed for users of Red Hat Enterprise Linux 5 in the 5.3 update, RHSA-2009:0225.

In accordance with the support policy, future security updates to Red Hat Enterprise Linux 5.2 Extended Update Support will only include issues of critical security impact.

* 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)

* a flaw was found in the Asynchronous Transfer Mode (ATM) subsystem.
A local, unprivileged user could use the flaw to listen on the same socket more than once, possibly causing a denial of service.
(CVE-2008-5079, Important)

* a race condition was found in the Linux kernel 'inotify' watch removal and umount implementation. This could allow a local, unprivileged user to cause a privilege escalation or a denial of service. (CVE-2008-5182, Important)

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