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.
