Scientific Linux Security Update : kernel on SL5.x i386/x86_64

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


Synopsis :

The remote Scientific Linux host is missing one or more security
updates.

Description :

This update fixes the following security issues :

- A NULL pointer dereference flaw was found in the
io_submit_one() function in the Linux kernel
asynchronous I/O implementation. A local, unprivileged
user could use this flaw to cause a denial of service.
(CVE-2010-3066, Moderate)

- A flaw was found in the xfs_ioc_fsgetxattr() function in
the Linux kernel XFS file system implementation. A data
structure in xfs_ioc_fsgetxattr() was not initialized
properly before being copied to user-space. A local,
unprivileged user could use this flaw to cause an
information leak. (CVE-2010-3078, Moderate)

- The exception fixup code for the __futex_atomic_op1,
__futex_atomic_op2, and futex_atomic_cmpxchg_inatomic()
macros replaced the LOCK prefix with a NOP instruction.
A local, unprivileged user could use this flaw to cause
a denial of service. (CVE-2010-3086, Moderate)

- A flaw was found in the tcf_act_police_dump() function
in the Linux kernel network traffic policing
implementation. A data structure in
tcf_act_police_dump() was not initialized properly
before being copied to user-space. A local, unprivileged
user could use this flaw to cause an information leak.
(CVE-2010-3477, Moderate)

- A missing upper bound integer check was found in the
sys_io_submit() function in the Linux kernel
asynchronous I/O implementation. A local, unprivileged
user could use this flaw to cause an information leak.
(CVE-2010-3067, Low)

This update also fixes several bugs.

The system must be rebooted for this update to take effect.
