RHEL 6 : kernel-rt (RHSA-2012:0670)

medium Nessus Plugin ID 76644

Synopsis

The remote Red Hat host is missing one or more security updates for kernel-rt.

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2012:0670 advisory.

- kernel: jbd2: unmapped buffer with _Unwritten or _Delay flags set can lead to DoS (CVE-2011-4086)

- kernel: fcaps: clear the same personality flags as suid when fcaps are used (CVE-2012-2123)

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

Solution

Update the RHEL kernel-rt package based on the guidance in RHSA-2012:0670.
