Synopsis
========
Several vulnerabilities were fixed in cvs, both in the server and in cvsbug.

Background
==========
CVS is a Concurrent Versioning System: CVS is a version control
system, which allows you to keep old versions of files (usually source
code), keep a log of who, when, and why changes occurred, etc., like
RCS or SCCS.

Description
===========
CAN-2005-2693: 
cvsbug in CVS 1.12.12 and earlier creates temporary files insecurely,
which allows local users to overwrite arbitrary files and execute
arbitrary code via a symlink attack.

CAN-2005-0753:
Buffer overflow in CVS allows remote attackers to execute arbitrary code.

Issue 224: 
The confirmed vulnerability could allow the execution of arbitrary
code on the CVS server, but only if a user already had commit access
and if one of the contrib scripts was installed improperly, a
condition which should have been quickly visible to any administrator.
 The complete description of the problem is here:
https://ccvs.cvshome.org/issues/show_bug.cgi?id=224.

Workaround
==========
There are no known workarounds at this time.

Affected packages
=================
cvs in all grimoires is affected. This is now fixed in all grimoires:
devel, test, stable-rc/0.2 and stable/0.1

Resolution
==========
All cvs users should upgrade to the latest available version:
         # scribe update
         # cast -c cvs
