Solution
Please Install the Updated Packages.
Insight
FUSE (Filesystem in Userspace) 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. (CVE-2010-3879, CVE-2011-0541, CVE-2011-0542, CVE-2011-0543)
Note: The util-linux-ng RHBA-2011:0699 update must also be installed to fully correct the above flaws.
All users should upgrade to these updated packages, which contain backported patches to correct these issues.
