Solution
Please Install the Updated Packages.
Insight
The kernel packages contain the Linux kernel, the core of any Linux operating system.
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)
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.
