Fedora Update Notification
FEDORA-2004-169
2004-06-11

Product : Fedora Core 1
Name : cvs
Version : 1.11.17
Release : 1
Summary : A version control system.

Description :
CVS (Concurrent Version System) is a version control system that
can record the history of your files (usually, but not always,
source code). CVS only stores the differences between versions,
instead of every version of every file you have ever created. CVS
also keeps a log of who, when, and why changes occurred.

CVS is very helpful for managing releases and controlling the
concurrent editing of source files among multiple authors. Instead
of providing version control for a collection of files in a single
directory, CVS provides version control for a hierarchical
collection of directories consisting of revision controlled files.
These directories and files can then be combined together to form a
software release.

Update Information:

While investigating a previously fixed vulnerability, Derek
Price discovered a flaw relating to malformed “Entry” lines which
lead to a missing NULL terminator. The Common Vulnerabilities and
Exposures project (cve.mitre.org/) has assigned the name
CAN-2004-0414 to this issue.

Stefan Esser and Sebastian Krahmer conducted an audit of CVS and
fixed a number of issues that may have had security
consequences.

Among the issues deemed likely to be exploitable were:

a double-free relating to the error_prog_name string
(CAN-2004-0416) — an argument integer overflow (CAN-2004-0417) —
out-of-bounds writes in serv_notify (CAN-2004-0418).

An attacker who has access to a CVS server may be able to
execute arbitrary code under the UID on which the CVS server is
executing.

Users of CVS are advised to upgrade to this updated package,
which updates the cvs package to version 1.11.17, which corrects
these issues.

Red Hat would like to thank Stefan Esser, Sebastian Krahmer, and
Derek Price for auditing, disclosing, and providing patches for
these issues.
