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: https://security-tracker.debian.org/tracker/heimdal
