    CVE ID         : CVE-2016-1254
    Debian Bug     : 848847
    
    It was discovered that Tor, a connection-based low-latency anonymous
    communication system, may read one byte past a buffer when parsing
    hidden service descriptors. This issue may enable a hostile hidden
    service to crash Tor clients depending on hardening options and malloc
    implementation.
    
    For the stable distribution (jessie), this problem has been fixed in
    version 0.2.5.12-4.
    
    For the testing (stretch) and unstable (sid) distributions, this
    problem has been fixed in version 0.2.9.8-2.
    
    We recommend that you upgrade your tor packages.
