    Package        : fuse
    CVE ID         : CVE-2016-1233
    
    Jann Horn discovered a vulnerability in the fuse (Filesystem in
    Userspace) package in Debian. The fuse package ships an udev rules
    adjusting permissions on the related /dev/cuse character device, making
    it world writable.
    
    This permits a local, unprivileged attacker to create an
    arbitrarily-named character device in /dev and modify the memory of any
    process that opens it and performs an ioctl on it.
    
    This in turn might allow a local, unprivileged attacker to escalate to
    root privileges.
    
    For the oldstable distribution (wheezy), the fuse package is not affected.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 2.9.3-15+deb8u2.
    
    For the testing distribution (stretch), this problem has been fixed
    in version 2.9.5-1.
    
    For the unstable distribution (sid), this problem has been fixed in
    version 2.9.5-1.
    
    We recommend that you upgrade your fuse packages.
