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"
References
