    Package        : fuse
    CVE ID         : CVE-2018-10906
    Debian Bug     : 904439
    
    Jann Horn discovered that FUSE, a Filesystem in USErspace, allows the
    bypass of the 'user_allow_other' restriction when SELinux is active
    (including in permissive mode). A local user can take advantage of this
    flaw in the fusermount utility to bypass the system configuration and
    mount a FUSE filesystem with the 'allow_other' mount option.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 2.9.7-1+deb9u1.
    
    We recommend that you upgrade your fuse packages.
    
    For the detailed security status of fuse please refer to its security
    tracker page at:
