In Mitre's CVE dictionary: CVE-2015-3202.
More information:

The patch applied for ntfs-3g to fix CVE-2015-3202 in DLA 226-1 was incomplete. This update corrects that problem. For reference the original advisory text follows.

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 Debian 6 Squeeze, these issues have been fixed in ntfs-3g version 1:2010.3.6-1+deb6u2
