RHSA-2010:0907-01: [RHSA-2010:0907-01] kernel buffer-overflow, race condition, denial-of-service

Product: Red Hat Enterprise Linux

Summary: Updated kernel packages that fix one security issue and four bugs are now available for Red Hat Enterprise Linux 5.4 Extended Update Support.

Description: The kernel packages contain the Linux kernel, the core of any Linux operating system. This update fixes the following security issue: * Buffer overflow flaws were found in the Linux kernel's implementation of the server-side External Data Representation (XDR) for the Network File System (NFS) version 4. An attacker on the local network could send a specially-crafted large compound request to the NFSv4 server, which could possibly result in a kernel panic (denial of service) or, potentially, code execution. (CVE-2010-2521, Important)

* A race condition existed when generating new process IDs with the result that the wrong process could have been signaled or killed accidentally, leading to various application faults. This update detects and disallows the reuse of PID numbers. (BZ#638865) Read more at www.criticalwatch.com
