CVE-2018-16860
Isaac Boukris and Andrew Bartlett discovered that Heimdal was susceptible to man-in-the-middle attacks caused by incomplete checksum validation. Details on the issue can be found in the Samba advisory at [link moved to references].
CVE-2019-12098
It was discovered that failure of verification of the PA-PKINIT-KX key exchange client-side could permit to perform man-in-the-middle attack.
For the stable distribution (stretch), these problems have been fixed in version 7.1.0+dfsg-13+deb9u3.
We recommend that you upgrade your heimdal packages.
For the detailed security status of heimdal please refer to its security tracker page at: [link moved to references]");
