Synopsis

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

Description

The remote Redhat Enterprise Linux 6 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2011:1694 advisory.

The libcap packages provide a library and tools for getting and setting POSIX capabilities.

It was found that capsh did not change into the new root when using the
--chroot option. An application started via the capsh --chroot command could use this flaw to escape the chroot restrictions. (CVE-2011-4099)

This update also fixes the following bug:

* Previously, the libcap packages did not contain the capsh(1) manual page.
With this update, the capsh(1) manual page is included. (BZ#730957)

All libcap users are advised to upgrade to these updated packages, which contain backported patches to correct these issues.

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 libcap package based on the guidance in RHSA-2011:1694.
