    Package        : fuse
    CVE ID         : CVE-2015-3202
    
    Tavis Ormandy discovered that FUSE, a Filesystem in USErspace, 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 2.9.0-2+deb7u2.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 2.9.3-15+deb8u1.
    
    For the testing distribution (stretch) and the unstable distribution
    (sid), this problem will be fixed soon.
    
    We recommend that you upgrade your fuse packages.
