SuSE 10 Security Update : Linux kernel (ZYPP Patch Number 8324)

This script is Copyright (C) 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 :

- kernel/taskstats.c in the Linux kernel allowed local
users to obtain sensitive I/O statistics by sending
taskstats commands to a netlink socket, as demonstrated
by discovering the length of another users password (a
side channel attack). (CVE-2011-2494)

- net/ipv6/netfilter/nf_conntrack_reasm.c in the Linux
kernel, when the nf_conntrack_ipv6 module is enabled,
allowed remote attackers to cause a denial of service
(NULL pointer dereference and system crash) via certain
types of fragmented IPv6 packets. (CVE-2012-2744)

- Use-after-free vulnerability in the xacct_add_tsk
function in kernel/tsacct.c in the Linux kernel allowed
local users to obtain potentially sensitive information
from kernel memory or cause a denial of service (system
crash) via a taskstats TASKSTATS_CMD_ATTR_PID command.
(CVE-2012-3510)

- The user_update function in security/keys/user_defined.c
in the Linux kernel 2.6 allowed local users to cause a
denial of service (NULL pointer dereference and kernel
oops) via vectors related to a user-defined key and
updating a negative key into a fully instantiated key.
(CVE-2011-4110)

- The ib_uverbs_poll_cq function in
drivers/infiniband/core/uverbs_cmd.c in the Linux kernel
did not initialize a certain response buffer, which
allowed local users to obtain potentially sensitive
information from kernel memory via vectors that cause
this buffer to be only partially filled, a different
vulnerability than CVE-2010-4649. (CVE-2011-1044)

- Heap-based buffer overflow in the udf_load_logicalvol
function in fs/udf/super.c in the Linux kernel allowed
remote attackers to cause a denial of service (system
crash) or possibly have unspecified other impact via a
crafted UDF filesystem. (CVE-2012-3400)

- The sock_alloc_send_pskb function in net/core/sock.c in
the Linux kernel did not properly validate a certain
length value, which allowed local users to cause a
denial of service (heap-based buffer overflow and system
crash) or possibly gain privileges by leveraging access
to a TUN/TAP device. (CVE-2012-2136)

- A small denial of service leak in dropping syn+fin
messages was fixed. (CVE-2012-2663)
