Synopsis:	Important: kernel security update
Issue date:	2009-08-27
CVE Names:	CVE-2009-2692 CVE-2009-2698

CVE-2009-2692 kernel: uninit op in SOCKOPS_WRAP() leads to privesc
CVE-2009-2698 kernel: udp socket NULL ptr dereference

These updated packages fix the following security issues:

* a flaw was found in the SOCKOPS_WRAP macro in the Linux kernel. This
macro did not initialize the sendpage operation in the proto_ops
structure correctly. A local, unprivileged user could use this flaw to
cause a local denial of service or escalate their privileges.
(CVE-2009-2692, Important)

* a flaw was found in the udp_sendmsg() implementation in the Linux
kernel when using the MSG_MORE flag on UDP sockets. A local,
unprivileged user could use this flaw to cause a local denial of service
or escalate their privileges. (CVE-2009-2698, Important)

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