Fedora Core 2: 2004-131 Critical Cvs Heap Overflow Issue

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.

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.
