Description

Updated e2fsprogs packages that fix several security issues are now available for Red Hat Enterprise Linux.

This update has been rated as having moderate security impact by the Red Hat Security Response Team.

The e2fsprogs packages contain a number of utilities for creating, checking, modifying, and correcting any inconsistencies in second and third extended (ext2/ext3) file systems.

Multiple integer overflow flaws were found in the way e2fsprogs processes file system content. If a victim opens a carefully crafted file system with a program using e2fsprogs, it may be possible to execute arbitrary code with the permissions of the victim. It may be possible to leverage this flaw in a virtualized environment to gain access to other virtualized hosts. (CVE-2007-5497)

Red Hat would like to thank Rafal Wojtczuk of McAfee Avert Research for responsibly disclosing these issues.

Users of e2fsprogs are advised to upgrade to these updated packages, which contain a backported patch to resolve these issues.
