Debian DSA-5344-1 : heimdal - security update

high Nessus Plugin ID 171237

Language:

Synopsis

The remote Debian host is missing one or more security-related updates.

Description

The remote Debian 11 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5344 advisory.

 Helmut Grohne discovered a flaw in Heimdal, an implementation of Kerberos 5 that aims to be compatible with MIT Kerberos. The backports of fixes for CVE-2022-3437 accidentally inverted important memory comparisons in the arcfour-hmac-md5 and rc4-hmac integrity check handlers for gssapi, resulting in incorrect validation of message integrity codes. For the stable distribution (bullseye), this problem has been fixed in version 7.7.0+dfsg-2+deb11u3. We recommend that you upgrade your heimdal packages. For the detailed security status of heimdal please refer to its security tracker page at: https://security- tracker.debian.org/tracker/heimdal

Tenable has extracted the preceding description block directly from the Debian security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Solution

Upgrade the heimdal packages.

For the stable distribution (bullseye), this problem has been fixed in version 7.7.0+dfsg-2+deb11u3.
