Debian DSA-3268-1 : ntfs-3g - security update

low Nessus Plugin ID 83785

Language:

Synopsis

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

Description

Tavis Ormandy discovered that NTFS-3G, a read-write NTFS driver for FUSE, 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 ntfs-3g packages.

For the oldstable distribution (wheezy), this problem has been fixed in version 1:2012.1.15AR.5-2.1+deb7u1. Note that this issue does not affect the binary packages distributed in Debian in wheezy as ntfs-3g does not use the embedded fuse-lite library.

For the stable distribution (jessie), this problem has been fixed in version 1:2014.2.15AR.2-1+deb8u1.
