An array index error, leading to heap-based buffer overflow was found in the way CVS version control system applied certain delta fragments changes from input file in the RCS (Revision Control System file) format. A local attacker could store a specially-crafted RCS file into the CVS repository and trick the remote victim to checkout (update their CVS repository tree) with this file, which could lead to arbitrary code execution with the privileges of the user running cvs client executable.

cvs-1.11.23-alt4 -> sisyphus: * Fri Dec 03 2010 Dmitry V. Levin <ldv@altlinux> 1.11.23-alt4 - Applied upstream fix to an array index error, leading to a heap-based buffer overflow, 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, this could result in arbitrary code execution with the privileges of the CVS server process on the system hosting the CVS repository when a remote user eventually checks out a revision of the affected file. Special thanks to Owl for the description. (CVE-2010-3846; closes: #24468).
