Mandrakelinux Advisory: ksymoops

Mandrakelinux Security Update Advisory

Package name: ksymoops
Advisory ID: MDKSA-2004:060
Date: June 10th, 2004
Affected versions: 10.0, 9.1, 9.2, Corporate Server 2.1

Problem Description:

Geoffrey Lee discovered a problem with the ksymoops-gznm script distributed with Mandrakelinux. The script fails to do proper checking when copying a file to the /tmp directory. Because of this, a local attacker can setup a symlink to point to a file that they do not have permission to remove. The problem is difficult to exploit because someone with root privileges needs to run ksymoops on a particular module for which a symlink for the same filename already exists.
