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 :

These new kernel packages contain fixes for the following security
issues :

- a flaw in the handling of IPv6 type 0 routing headers
that allowed remote users to cause a denial of service
that led to a network amplification between two routers
(CVE-2007-2242, Important).

- a flaw in the nfnetlink_log netfilter module that
allowed a local user to cause a denial of service
(CVE-2007-1496, Important).

- a flaw in the flow list of listening IPv6 sockets that
allowed a local user to cause a denial of service
(CVE-2007-1592, Important).

- a flaw in the handling of netlink messages that allowed
a local user to cause a denial of service (infinite
recursion) (CVE-2007-1861, Important).

- a flaw in the IPv4 forwarding base that allowed a local
user to cause an out-of-bounds access (CVE-2007-2172,
Important).

- a flaw in the nf_conntrack netfilter module for IPv6
that allowed remote users to bypass certain netfilter
rules using IPv6 fragments (CVE-2007-1497, Moderate).

In addition to the security issues described above, fixes for the
following have been included :

- a regression in ipv6 routing.

- an error in memory initialization that caused gdb to
output inaccurate backtraces on ia64.

- the nmi watchdog timeout was updated from 5 to 30
seconds.

- a flaw in distributed lock management that could result
in errors during virtual machine migration.

- an omitted include in kernel-headers that led to compile
failures for some packages.
