RHEL 2.1 / 3 : cvs (RHSA-2004:233)

This script is Copyright (C) 2004-2014 Tenable Network Security, Inc.


Synopsis :

The remote Red Hat host is missing a security update.

Description :

An updated cvs package that fixes several server vulnerabilities,
which could be exploited by a malicious client, is now available.

CVS is a version control system frequently used to manage source code
repositories.

While investigating a previously fixed vulnerability, Derek Price
discovered a flaw relating to malformed 'Entry' lines which lead to a
missing NULL terminator. The Common Vulnerabilities and Exposures
project (cve.mitre.org) has assigned the name CVE-2004-0414 to this
issue.

Stefan Esser and Sebastian Krahmer conducted an audit of CVS and fixed
a number of issues that may have had security consequences.

Among the issues deemed likely to be exploitable were :

-- a double-free relating to the error_prog_name string
(CVE-2004-0416) -- an argument integer overflow (CVE-2004-0417) --
out-of-bounds writes in serv_notify (CVE-2004-0418).

An attacker who has access to a CVS server may be able to execute
arbitrary code under the UID on which the CVS server is executing.

Users of CVS are advised to upgrade to this updated package, which
contains backported patches correcting these issues.

Red Hat would like to thank Stefan Esser, Sebastian Krahmer, and Derek
Price for auditing, disclosing, and providing patches for these
issues.
