heimdal vulnerabilities
Isaac Boukris and Andrew Bartlett discovered that Heimdal's KDC was
not properly performing checksum algorithm verifications in the
S4U2Self extension module. An attacker could possibly use this issue
to perform a machine-in-the-middle attack and request S4U2Self
tickets for any user known by the application. This issue only
affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM and Ubuntu 18.04 LTS.
(CVE-2018-16860)
It was discovered that Heimdal was not properly handling the
verification of key exchanges when an anonymous PKINIT was being
used. An attacker could possibly use this issue to perform a
machine-in-the-middle attack and expose sensitive information.
This issue only affected Ubuntu 14.04 ESM, Ubuntu 16.04 ESM and
Ubuntu 18.04 LTS. (CVE-2019-12098)

FAQ: Is Azure Linux the only Microsoft product that includes this open-source library and is therefore potentially affected by this vulnerability?
One of the main benefits to our customers who choose to use the Azure Linux distro is the commitment to keep it up to date with the most recent and most secure versions of the open source libraries with which the distro is composed. Microsoft is committed to transparency in this work which is why we began publishing CSAF/VEX in October 2025. See this blog post for more information. If impact to additional products is identified,
