Security database references:
In Mitre's CVE dictionary: CVE-2015-3202.
More information:

Tavis Ormandy discovered that FUSE, a Filesystem in USErspace, does not scrub the environment before executing mount or umount with elevated privileges. A local user can take advantage of this flaw to overwrite arbitrary files and gain elevated privileges by accessing debugging features via the environment that would not normally be safe for unprivileged users.

For the old-oldstable distribution (squeeze-lts), this problem has been fixed in version 2.8.4-1.1+deb6u1.

We recommend that you upgrade your fuse packages.
