Synopsis

The remote Red Hat host is missing a security update for kernel.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:0329 advisory.

The kernel packages contain the Linux kernel, the core of any Linux operating system.

This update fixes the following security issue:

* A use-after-free flaw was found in the Linux kernel's RPC server sockets implementation. A remote attacker could use this flaw to trigger a denial of service by sending a corrupted packet to a target system.

Red Hat would like to thank Adam Prince for reporting this issue.
