===================================================================== Red Hat Security Advisory
Synopsis: Moderate: cvs security update Advisory ID: RHSA-2010:0918-01 Product: Red Hat Enterprise Linux Advisory URL: https://rhn.redhat.com/errata/RHSA-2010-0918.html Issue date: 2010-11-29 CVE Names: CVE-2010-3846 =====================================================================
1. Summary:
An updated cvs package that fixes one security issue is now available for Red Hat Enterprise Linux 6.
The Red Hat Security Response Team 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 Desktop (v. 6) - i386, x86_64 Red Hat Enterprise Linux HPC Node (v. 6) - x86_64 Red Hat Enterprise Linux Server (v. 6) - i386, ppc64, s390x, x86_64 Red Hat Enterprise Linux Workstation (v. 6) - i386, x86_64
3. Description:
Concurrent Version System (CVS) is a version control system that can record the history of your files.
An array index error, leading to a heap-based buffer overflow, was found in the way CVS applied certain delta fragment changes from input files in the RCS (Revision Control System file) format. If an attacker in control of a CVS repository stored a specially-crafted RCS file in that repository, and then tricked a remote victim into checking out (updating their CVS repository tree) a revision containing that file, it could lead to arbitrary code execution with the privileges of the CVS server process on the system hosting the CVS repository. (CVE-2010-3846)
Red Hat would like to thank Ralph Loader for reporting this issue.
All users of cvs are advised to upgrade to this updated package, which contains a backported patch to correct this issue.
4. Solution:
Before applying this update, make sure all previously-released errata relevant to your system have been applied.
