RHEL 5 : kernel (RHSA-2010:0792)

high Nessus Plugin ID 50340

Language:

Synopsis

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

Description

The remote Redhat Enterprise Linux 5 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2010:0792 advisory.

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

 This update fixes the following security issue:

 * The rds_page_copy_user() function in the Linux kernel Reliable Datagram Sockets (RDS) protocol implementation was missing sanity checks. A local, unprivileged user could use this flaw to escalate their privileges.
 (CVE-2010-3904, Important)

 Red Hat would like to thank Dan Rosenberg of Virtual Security Research for reporting this issue.

 Users should upgrade to these updated packages, which contain a backported patch to correct this issue. The system must be rebooted for this update to take effect.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL kernel package based on the guidance in RHSA-2010:0792.
