Synopsis
========
A command injection vulnerability in CVS may 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-r12 >= 1.12.12-r12
Description
===========
It was discovered that when CVS is configured to use SSH for remote
repositories it allows remote attackers to execute arbitrary code
through a repository URL with a specially crafted hostname.
Impact
======
A remote attacker, by enticing a user to clone a specially crafted
repository, could possibly execute arbitrary code with the privileges
of the process.
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-r12"
