It is recommended that administrators running hivex check for an updated version of the software for their operating system. - --------------------------BEGIN INCLUDED TEXT-------------------- - -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ===================================================================== Red Hat Security Advisory Synopsis: Moderate: hivex security, bug fix, and enhancement update Advisory ID: RHSA-2015:0301-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2015-0301.html 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 (v. 7) - x86_64 Red Hat Enterprise Linux Client Optional (v. 7) - x86_64 Red Hat Enterprise Linux Server (v. 7) - x86_64 Red Hat Enterprise Linux Server Optional (v. 7) - x86_64 Red Hat Enterprise Linux Workstation (v. 7) - x86_64 Red Hat Enterprise Linux Workstation Optional (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: Before applying this update, make sure all previously released errata relevant to your system have been applied. For details on how to apply this update, refer to: https://access.redhat.com/articles/11258 5. Bugs fixed (https://bugzilla.redhat.com/): 1023978 - Rebase hivex in RHEL 7.1 1099286 - typo error in man page 1145056 - hivexml generate "Argument list too long" on some Windows Registry 1158992 - CVE-2014-9273 hivex: missing checks for small-sized files [rhel-7.1] 1167756 - CVE-2014-9273 hivex: missing checks for small-sized files 6.
