Subject: [bug#62760] [PATCH 1/3] gnu: heimdal: Update to 7.8.0.
Date: Mon, 10 Apr 2023 12:52:24 -0700

Fixes CVE-2022-44640 [1] "Heimdal KDC: invalid free in ASN.1 codec." The
upstream release announcement calls it "a severe vulnerability, possibly a
10.0 on the Common Vulnerability Scoring System (CVSS) v3."

The upstream developers further "believe it should be possible to get an RCE
[remote code execution] on a KDC, which means that credentials can be
compromised that can be used to impersonate anyone in a realm or forest of
realms." "While no zero-day exploit is known, such an exploit will likely be
available soon after public disclosure." [2]
