Vulnerability Name:

CCN-611

Published:1997-10-01
Updated:1997-10-01
Summary:This issue contains two parts:

Red Hat calls the printfilter software package when any file is being printed. After determining the file type, printfilter applies the appropriate filter to the file so the file can be printed properly. Some filters write in the /tmp directory, therefore local users can create system links that will overwrite files with uid bin and gid root.

Groff requests allow local as well as remote users execute programs as uid bin and gid root, which can easily lead to root access.
