Synopsis
=======

Several serious vulnerabilities have been found in CVS, which may allow an attacker to remotely compromise a CVS server or cause a DoS.

Background
=========

CVS (Concurrent Versions System) is an open-source network-transparent version control system. It contains both a client utility and a server.

Affected packages
================

-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 dev-util/cvs lt; 1.11.18-r1 gt;= 1.11.18-r1

Description
==========

Alen Zukich has discovered several serious security issues in CVS, including at least one buffer overflow (CAN-2005-0753), memory leaks and a NULL pointer dereferencing error.

Impact
=====

An attacker could exploit these vulnerabilities to cause a Denial of Service or execute arbitrary code with the permissions of the CVS pserver or the authenticated user (depending on the connection method used).

Workaround
=========

There is no known workaround at this time.

Resolution
=========

All CVS users should upgrade to the latest version:

# emerge --sync
# emerge --ask --oneshot --verbose "gt;=dev-util/cvs-1.11.18-r1"
