Package : heimdal
Version : 1.6~git20120403+dfsg1-2+deb7u1
CVE ID : CVE-2017-11103
Debian Bug : 868208
Jeffrey Altman, Viktor Duchovni and Nico Williams identified a mutual
authentication bypass vulnerability in Heimdal Kerberos. Also known as
Orpheus' Lyre, this vulnerability could be used by an attacker to mount
a service impersonation attack on the client if he's on the network
path between the client and the service.
More details can be found on the vulnerability website
(https://orpheus-lyre.info/).
For Debian 7 "Wheezy", these problems have been fixed in version
1.6~git20120403+dfsg1-2+deb7u1.
We recommend that you upgrade your heimdal packages.
