RHEL 6 : cvs (RHSA-2010:0918)

high Nessus Plugin ID 50840

Language:

Synopsis

The remote Red Hat host is missing a security update for cvs.

Description

The remote Redhat Enterprise Linux 6 host has a package installed that is affected by a vulnerability as referenced in the RHSA-2010:0918 advisory.

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.

Tenable has extracted the preceding description block directly from the Red Hat Enterprise Linux security advisory.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version number.

Solution

Update the RHEL cvs package based on the guidance in RHSA-2010:0918.
