Fedora Core Advisory: cvsJun 12, 2004, 19:28 (0 Talkback[s])Fedora Update Notification FEDORA-2004-169 2004-06-11 Product : Fedora Core 1 Description : 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:
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.
