Debian DLA-1027-1 : heimdal security update (Orpheus' Lyre)

high Nessus Plugin ID 101553

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
