Description

It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS2023-2026-1586 advisory.

 Potential use-after-free in DANE client code (CVE-2026-28387)

 NULL Pointer Dereference When Processing a Delta CRL

Tenable has extracted the preceding description block directly from the tested product 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

Run 'dnf update openssl --releasever 2023.11.20260413' or or 'dnf update --advisory ALAS2023-2026-1586 --releasever 2023.11.20260413' to update your system.
