Mandriva: Updated fuse packages fix vulnerability Print E-mail
User Rating:      How can I rate this item?
Posted by Benjamin D. Thomas   
Mandrake 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.

 Mandriva Linux Security Advisory                         MDKSA-2005:216

 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.
