Red Hat Security Advisory

Synopsis: Important: kernel security and bug fix update
Advisory ID: RHSA-2007:0347-01
Advisory URL: https://rhn.redhat.com/errata/RHSA-2007-0347.html
Issue date: 2007-05-16
Updated on: 2007-05-16
Product: Red Hat Enterprise Linux
CVE Names: CVE-2007-1496 CVE-2007-1497 CVE-2007-1592
CVE-2007-1861 CVE-2007-2172 CVE-2007-2242
- ---------------------------------------------------------------------

1. Summary:

Updated kernel packages that fix security issues and bugs in the Red Hat
Enterprise Linux 5 kernel are now available.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux Desktop (v. 5 client) - i386, noarch, x86_64
RHEL Desktop Workstation (v. 5 client) - i386, x86_64
Red Hat Enterprise Linux (v. 5 server) - i386, ia64, noarch, ppc, s390x, x86_64

3. Problem description:

The Linux kernel handles the basic functions of the operating system.

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.

Red Hat Enterprise Linux 5 users are advised to upgrade to these packages,
which contain backported patches to correct these issues.

4. Solution:
