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     < 1.11.18-r1                       >= 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 ">=dev-util/cvs-1.11.18-r1"
