CVE-2010-3846
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.
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.
