A directory traversal vulnerability was discovered in cgit. By default, cgit is not affected. However, if cgit is configured to use a readme file from a filesystem path instead of from the git repo itself then files outside of the repository can be read.
Refer to the discussion on oss-security for further details :
http://www.openwall.com/lists/oss-security/2013/05/25/3
Note that Tenable Network Security has extracted the preceding description block directly from the Fedora security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
