|Bugzilla:||678144: CVE-2011-0714 kernel: deficiency in handling of invalid data packets in lockd|
The MITRE CVE dictionary describes this issue as:
Use-after-free vulnerability in a certain Red Hat patch for the RPC server sockets functionality in the Linux kernel 2.6.32 on Red Hat Enterprise Linux (RHEL) 6 might allow remote attackers to cause a denial of service (crash) via malformed data in a packet, related to lockd and the svc_xprt_received function.
This issue only affects Red Hat Enterprise Linux 6 as we did not properly backport upstream commit b48fa6b9. The versions of the Linux kernel as shipped with Red Hat Enterprise Linux 4, 5, and Red Hat Enterprise MRG are not affected.
