Debian Security Advisory DSA-3268-1 security@debian.org http://www.debian.org/security/ Salvatore Bonaccorso May 22, 2015 http://www.debian.org/security/faq


Package : ntfs-3g CVE ID : CVE-2015-3202 Debian Bug : 786475

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.

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.

For the testing distribution (stretch) and the unstable distribution (sid), this problem will be fixed soon.

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