Detailsinfo

A vulnerability was found in FreeBSD 4.5 (Operating System). It has been classified as problematic. This affects an unknown code block of the file /tmp of the component X Window. The manipulation with an unknown input leads to a symlink vulnerability. CWE is classifying the issue as CWE-61.
