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"
References
