The remote Red Hat host is missing one or more security updates.
Updated kernel packages that fix two security issues and a bug are now
available for Red Hat Enterprise Linux 5.
This update has been rated as having important security impact by the
Red Hat Security Response Team.
The kernel packages contain the Linux kernel, the core of any Linux
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.
* 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)
Red Hat would like to thank Tavis Ormandy and Julien Tinnes of the
Google Security Team for responsibly reporting these flaws.
These updated packages also fix the following bug :
* in the dlm code, a socket was allocated in tcp_connect_to_sock(),
but was not freed in the error exit path. This bug led to a memory
leak and an unresponsive system. A reported case of this bug occurred
after running 'cman_tool kill -n [nodename]'. (BZ#515432)
Users should upgrade to these updated packages, which contain
backported patches to correct these issues. The system must be
rebooted for this update to take effect.
