Issue date: 2015-03-05

CVE Names: CVE-2014-9273

=====================================================================

 

1. Summary:

 

Updated hivex packages that fix one security issue, several bugs, and add

various enhancements are now available for Red Hat Enterprise Linux 7.

 

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.

 

2. Relevant releases/architectures:

Red Hat Enterprise Linux Client Optional (v. 7) - x86_64

Red Hat Enterprise Linux Server (v. 7) - x86_64

3. Description:

 

Hive files are undocumented binary files that Windows uses to store the

Windows Registry on disk. Hivex is a library that can read and write to

these files.

 

It was found that hivex attempted to read 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.

 

The hivex package has been upgraded to upstream version 1.3.10, which

provides a number of bug fixes and enhancements over the previous version.

(BZ#1023978)

 

This update also fixes the following bugs:

 

* Due to an error in the hivex_value_data_cell_offset() function, the hivex

utility could, in some cases, print an "Argument list is too long" message

and terminate unexpectedly when processing hive files from the Windows

Registry. This update fixes the underlying code and hivex now processes

hive files as expected. (BZ#1145056)

 

* A typographical error in the Win::Hivex.3pm manual page has been

corrected. (BZ#1099286)

 

Users of hivex are advised to upgrade to these updated packages, which

correct these issues and adds these enhancements.

 

4. Solution:
