Synopsis
========

A heap-based buffer overflow in CVS might allow remote attackers to
execute arbitrary code.

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-vcs/cvs < 1.12.12-r11 >= 1.12.12-r11

Description
===========

A heap-based buffer overflow was discovered in the proxy_connect
function in src/client.c in CVS.

Impact
======

An attacker, utilizing a remote HTTP proxy server, could cause a Denial
of Service condition or possibly execute arbitrary code via a crafted
HTTP response.

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-vcs/cvs-1.12.12-r11”
