    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.
