RHSA-2015:1378 - Security Advisory

Topic

Updated hivex packages that fix one security issue and one bug are now
available for Red Hat Enterprise Linux 6.

Red Hat Product Security has rated this update as having Moderate security
impact. A Common Vulnerability Scoring System (CVSS) base score, which
gives a detailed severity rating, is available from the CVE link in the
References section.

Description

Hivex is a library that can read and write Hive files, undocumented binary
files that Windows uses to store the Windows Registry on disk.

It was found that hivex attempted to read, and possibly write, beyond its
allocated buffer when reading a hive file with a very small size or with a
truncated or improperly formatted content. An attacker able to supply a
specially crafted hive file to an application using the hivex library could
possibly use this flaw to execute arbitrary code with the privileges of the
user running that application. (CVE-2014-9273)

Red Hat would like to thank Mahmoud Al-Qudsi of NeoSmart Technologies for
reporting this issue.

This update also fixes the following bug:

• The hivex(3) man page previously contained a typographical error. This

update fixes the typo. (BZ#1164693)

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