SuSE 11 Security Update : Linux kernel (SAT Patch Numbers 1212 / 1218 / 1219)

This script is Copyright (C) 2009-2016 Tenable Network Security, Inc.


Synopsis :

The remote SuSE 11 host is missing one or more security updates.

Description :

The SUSE Linux Enterprise 11 Kernel was updated to 2.6.27.29 fixing
various bugs and security issues.

The following security issues were fixed :

- A missing NULL pointer check in the socket sendpage
function can be used by local attackers to gain root
privileges. (CVE-2009-2692)

- A kernel stack overflow when mounting eCryptfs
filesystems in parse_tag_11_packet() was fixed. Code
execution might be possible of ecryptfs is in use.
(CVE-2009-2406)

- A kernel heap overflow when mounting eCryptfs
filesystems in parse_tag_3_packet() was fixed. Code
execution might be possible of ecryptfs is in use.
(CVE-2009-2407)

The compiler option -fno-delete-null-pointer-checks was added to the
kernel build, and the -fwrapv compiler option usage was fixed to be
used everywhere. This works around the compiler removing checks too
aggressively.

- A crash in the r8169 driver when receiving large packets
was fixed. This is probably exploitable only in the
local network. (CVE-2009-1389)

No CVE yet: A sigaltstack kernel memory disclosure was fixed.

The NULL page protection using mmap_min_addr was enabled (was disabled
before).

This update also adds the Microsoft Hyper-V drivers from upstream.

Additionaly a lot of bugs were fixed.
