Debian DLA-238-1 : fuse security update

low Nessus Plugin ID 84023

Language:

Synopsis

The remote Debian host is missing a security 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.

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected fuse-utils, libfuse-dev, and libfuse2 packages.
