SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 7812)

This script is Copyright (C) 2011-2012 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 10 host is missing a security-related patch.

Description :

This Linux kernel update fixes various security issues and bugs in the
SUSE Linux Enterprise 10 SP4 kernel.

The following security issues have been fixed :

- A USB string descriptor overflow in the auerwald USB
driver was fixed, which could be used by physically
proximate attackers to cause a kernel crash.
(CVE-2009-4067)

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

- A malicious CIFS server could cause a integer overflow
on the local machine on directory index operations, in
turn causing memory corruption. (CVE-2011-3191)

- 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.
(CVE-2011-1776)

The following non-security issues have been fixed :

- md: fix deadlock in md/raid1 and md/raid10 when handling
a read error. (bnc#628343)

- md: fix possible raid1/raid10 deadlock on read error
during resync. (bnc#628343)

- Add timeo parameter to /proc/mounts for nfs filesystems.
(bnc#616256)

- virtio: indirect ring entries
(VIRTIO_RING_F_INDIRECT_DESC). (bnc#713876)

- virtio: teach virtio_has_feature() about transport
features. (bnc#713876)

- nf_nat: do not add NAT extension for confirmed
conntracks. (bnc#709213)

- 8250: Oxford Semiconductor Devices. (bnc#717126)

- 8250_pci: Add support for the Digi/IBM PCIe 2-port
Adapter. (bnc#717126)

- 8250: Fix capabilities when changing the port type.
(bnc#717126)

- 8250: Add EEH support. (bnc#717126)

- xfs: fix memory reclaim recursion deadlock on locked
inode buffer. (bnc#699355 / bnc#699354 / bnc#721830)

- ipmi: do not grab locks in run-to-completion mode.
(bnc#717421)

- cifs: add fallback in is_path_accessible for old
servers. (bnc#718028)

- cciss: do not attempt to read from a write-only
register. (bnc#683101)

- s390: kernel: System hang if hangcheck timer expires
(bnc#712009,LTC#74157).

- s390: kernel: NSS creation with initrd fails
(bnc#712009,LTC#74207).

- s390: kernel: remove code to handle topology interrupts
(bnc#712009,LTC#74440).

- xen: Added 1083-kbdfront-absolute-coordinates.patch.
(bnc#717585)

- acpi: Use a spinlock instead of mutex to guard gbl_lock
access. (bnc#707439)

- Allow balance_dirty_pages to help other filesystems.
(bnc#709369)

- nfs: fix congestion control. (bnc#709369)

- NFS: Separate metadata and page cache revalidation
mechanisms. (bnc#709369)

- jbd: Fix oops in journal_remove_journal_head().
(bnc#694315)

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

- xen/x86: replace order-based range checking of M2P table
by linear one.

- xen/x86: use dynamically adjusted upper bound for
contiguous regions. (bnc#635880)

- Fix type in
patches.fixes/libiscsi-dont-run-scsi-eh-if-iscsi-task-is
-making-progress.

- s390: cio: Add timeouts for internal IO
(bnc#701550,LTC#72691).

- s390: kernel: first time swap use results in heavy
swapping (bnc#701550,LTC#73132).

- s390: qeth: wrong number of output queues for
HiperSockets (bnc#701550,LTC#73814).
