Título:	RedHat Security Advisory RHSA-2010:0893
Resumen:	NOSUMMARY
Descripción:	Description: The remote host is missing updates announced in advisory RHSA-2010:0893. 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) This update also fixes the following bugs: * 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#638864) * When multiple JBD-based (Journaling Block Device) file systems were mounted concurrently, and no other JBD-based file systems were already mounted, a race could occur between JBD slab cache creation and deletion. (BZ#645653) * A missing memory barrier caused a race condition in the AIO subsystem between the read_events() and aio_complete() functions. This may have caused a thread in read_events() to sleep indefinitely, possibly causing an application hang. (BZ#638868) 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. Solution: Please note that this update is available via Red Hat Network.
