CBL Mariner 2.0 Security Update: heimdal (CVE-2022-45142)

high Nessus Plugin ID 173540

Synopsis

The remote CBL Mariner host is missing one or more security updates.

Description

The version of heimdal installed on the remote CBL Mariner 2.0 host is prior to tested version. It is, therefore, affected by a vulnerability as referenced in the CVE-2022-45142 advisory.

 - The fix for CVE-2022-3437 included changing memcmp to be constant time and a workaround for a compiler bug by adding != 0 comparisons to the result of memcmp. When these patches were backported to the heimdal-7.7.1 and heimdal-7.8.0 branches (and possibly other branches) a logic inversion sneaked in causing the validation of message integrity codes in gssapi/arcfour to be inverted. (CVE-2022-45142)

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

Solution

Update the affected packages.
