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

Description :

This update fixes the following security issues :

- A flaw was found in the Linux kernel's garbage collector
for AF_UNIX sockets. A local, unprivileged user could
use this flaw to trigger a denial of service
(out-of-memory condition). (CVE-2010-4249, Moderate)

- A flaw was found in the Linux kernel's networking
subsystem. If the number of packets received exceeded
the receiver's buffer limit, they were queued in a
backlog, consuming memory, instead of being discarded. A
remote attacker could abuse this flaw to cause a denial
of service (out-of-memory condition). (CVE-2010-4251,

- A missing initialization flaw was found in the
ethtool_get_regs() function in the Linux kernel's
ethtool IOCTL handler. A local user who has the
CAP_NET_ADMIN capability could use this flaw to cause an
information leak. (CVE-2010-4655, Low)

This update also fixes several bugs.

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

update. We apologize for this. yum --enablerepo=sl-testing update
