Debian Security Advisory DSA 715-1 security@debian.org
http://www.debian.org/security/ Martin Schulze
April 27th, 2005 http://www.debian.org/security/faq
- - --------------------------------------------------------------------------
Package : cvs
Vulnerability : serveral
Problem-Type : remote
Debian-specific: yes
CVE IDs : CAN-2004-1342 CAN-2004-1343
Debian Bug : 260200
Several problems have been discovered in the CVS server, which serves
the popular Concurrent Versions System. The Common Vulnerability and
Exposures project identifies the following problems:
CAN-2004-1342
Maks Polunin and Alberto Garcia discovered independently that
using the pserver access method in connection with the repouid
patch that Debian uses it is possible to bypass the password and
gain access to the repository in question.
CAN-2004-1343
Alberto Garcia discovered that a remote user can cause the cvs
server to crash when the cvs-repouids file exists but does not
contain a mapping for the current repository, which can be used as
a denial of service attack.
For the stable distribution (woody) these problems have been fixed in
version 1.11.1p1debian-10.
For the unstable distribution (sid) these problems have been fixed in
version 1.12.9-11.
We recommend that you upgrade your cvs package.
