vuln-type: potential data corruption when installed seduid root
problem-scope: local
debian-specifc: no
cve: CVE-2005-3531
vendor-advisory: 
testing-fix: 2.3.0-4.2etch1
sid-fix: 2.4.1-0.1
upgrade: apt-get upgrade

Thomas Biege discovered that fusermount in FUSE before 2.4.1, if installed
setuid root, allows local users to corrupt /etc/mtab and possibly modify mount
options by performing a mount over a directory whose name contains certain
special characters

Successful exploitation could result in a denial of service if mount options
become unusable. An attacker can also exploit this issue to add arbitrary mount
points that could grant the attacker read and possibly write access to
otherwise restricted or privileged mount points. Other attacks are also
possible.
