Mandriva Linux Security Advisory MDKSA-2005:216
http://www.mandriva.com/security/
_______________________________________________________________________

Package : fuse
Date : November 24, 2005
Affected: 2006.0
_______________________________________________________________________

Problem Description:

Thomas Beige found that fusermount failed to securely handle special
characters specified in mount points, which could allow a local
attacker to corrupt the contents of /etc/mtab by mounting over a
maliciously-named directory using fusermount. This could potentially
allow the attacker to set unauthorized mount options.

This is only possible when fusermount is installed setuid root, which
is the case in Mandriva Linux.

The updated packages have been patched to address these problems.
