Debian DSA-3266-1 : fuse - security update

low Nessus Plugin ID 83775

Language:

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the fuse packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 2.9.0-2+deb7u2.

For the stable distribution (jessie), this problem has been fixed in version 2.9.3-15+deb8u1.
