How to fix?

Upgrade RHEL:6 fuse-libs to version 0:2.8.3-3.el6_1 or higher.
This issue was patched in RHSA-2011:1083.

NVD Description

Note: Versions mentioned in the description apply only to the upstream fuse-libs package and not the fuse-libs package as distributed by RHEL. See How to fix? for RHEL:6 relevant fixed versions and status.

Certain legacy functionality in fusermount in fuse 2.8.5 and earlier, when util-linux does not support the --no-canonicalize option, allows local users to bypass intended access restrictions and unmount arbitrary directories via a symlink attack.
