Patch for udisks tackles critical vulnerability on Red Hat 6; users advised to implement it without delay.
Updated udisks packages that fix one security issue are now available for Red Hat Enterprise Linux 6

Solution

Before applying this update, make sure all previously released errata relevant to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red Hat Network to apply this update are available at https://access.redhat.com/site/articles/11258

Summary

The udisks package provides a daemon, a D-Bus API, and command line utilities for managing disks and storage devices.
A stack-based buffer overflow flaw was found in the way udisks handled files with long path names. A malicious, local user could use this flaw to create a specially crafted directory structure that, when processed by the udisks daemon, could lead to arbitrary code execution with the privileges of the udisks daemon (root). (CVE-2014-0004)
This issue was discovered by Florian Weimer of the Red Hat Product Security Team.
All udisks users are advised to upgrade to these updated packages, which contain a backported patch to correct this issue.
