(RHSA-2010:0918) Moderate: cvs security update

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.
