Debian DLA-815-1 : ntfs-3g security update

high Nessus Plugin ID 96963

Language:

Synopsis

The remote Debian host is missing a security update.

Description

Jann Horn of Google Project Zero discovered that NTFS-3G, a read-write NTFS driver for FUSE, does not scrub the environment before executing modprobe with elevated privileges. A local user can take advantage of this flaw for local root privilege escalation.

For Debian 7 'Wheezy', these problems have been fixed in version 1:2012.1.15AR.5-2.1+deb7u3.

We recommend that you upgrade your ntfs-3g 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 packages.
