    Package        : heimdal
    CVE ID         : CVE-2017-17439
    Debian Bug     : 878144
    
    Michael Eder and Thomas Kittel discovered that Heimdal, an
    implementation of Kerberos 5 that aims to be compatible with MIT
    Kerberos, did not correctly handle ASN.1 data. This would allow an
    unauthenticated remote attacker to cause a denial of service (crash of
    the KDC daemon) by sending maliciously crafted packets.
    
    For the stable distribution (stretch), this problem has been fixed in
    version 7.1.0+dfsg-13+deb9u2.
    
    We recommend that you upgrade your heimdal packages.
    
    For the detailed security status of heimdal please refer to
    its security tracker page at:
