Synopsis:	Important: kernel security and bug fix update
Issue date:	2007-05-16
CVE Names:	CVE-2007-1496 CVE-2007-1497 CVE-2007-1592
		CVE-2007-1861 CVE-2007-2172 CVE-2007-2242

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.
