Synopsis

The remote openSUSE host is missing a security update.

Description

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

Following security issues have been fixed: CVE-2011-1833: Added a kernel option to ensure ecryptfs is mounting only on paths belonging to the current ui, which would have allowed local attackers to potentially gain privileges via symlink attacks.

CVE-2011-3363: Always check the path in CIFS mounts to avoid interesting filesystem path interaction issues and potential crashes.

CVE-2011-2918: In the perf framework software event overflows could deadlock or delete an uninitialized timer.

CVE-2011-3353: In the fuse filesystem, FUSE_NOTIFY_INVAL_ENTRY did not check the length of the write so the message processing could overrun and result in a BUG_ON() in fuse_copy_fill(). This flaw could be used by local users able to mount FUSE filesystems to crash the system.

CVE-2011-3191: A signedness issue in CIFS could possibly have lead to to memory corruption, if a malicious server could send crafted replies to the host.

CVE-2011-1776: The is_gpt_valid function in fs/partitions/efi.c in the Linux kernel did not check the size of an Extensible Firmware Interface (EFI) GUID Partition Table (GPT) entry, which allowed physically proximate attackers to cause a denial of service (heap-based buffer overflow and OOPS) or obtain sensitive information from kernel heap memory by connecting a crafted GPT storage device, a different vulnerability than CVE-2011-1577.

Following non security bugs were fixed :

- drm/radeon/kms: Fix I2C mask definitions (bnc#712023).

- ext4: Fix max file size and logical block counting of extent format file (bnc#706374).

- TTY: pty, fix pty counting (bnc#711203).

- Update Xen patches to 2.6.34.10.

- xen/blkfront: fix data size for xenbus_gather in connect().

- xen/xenbus: fix xenbus_transaction_start() hang caused by double xenbus_transaction_end().

- xen/blkback: don't fail empty barrier requests.

- xen/blktap: fix locking (bnc#685276).

- xen/xenbus: don't BUG() on user mode induced conditions (bnc#696107).

- xen/blkfront: avoid NULL de-reference in CDROM ioctl handling (bnc#701355).

- intr-remap: allow disabling source id checking (bnc#710352).

Solution

Update the affected kernel packages.
