"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."
