Fedora: 2,1: cvs Heap overflow vulnerability
Summary
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:
Stefan Esser discovered a flaw in cvs where malformed "Entry" lines
could cause a heap overflow. An attacker who has access to a CVS
server could use this flaw to execute arbitrary code under the UID
which the CVS server is executing. The Common Vulnerabilities and
Exposures project (cve.mitre.org) has assigned the name CAN-2004-0396
to this issue.
This update includes a patch by Derek Price, based on a patch by
Stefan Esser, which corrects this flaw.
