Red Hat Security Advisory 2011-1083-01

Posted Jul 21, 2011

Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2011-1083-01 - FUSE can implement a fully functional file system in a user-space program. These packages provide the mount utility, fusermount, the tool used to mount FUSE file systems. Multiple flaws were found in the way fusermount handled the mounting and unmounting of directories when symbolic links were present. A local user in the fuse group could use these flaws to unmount file systems, which they would otherwise not be able to unmount and that were not mounted using FUSE, via a symbolic link attack.
