openSUSE 16 Security Update : erlang (openSUSE-SU-2026:20907-1)

high Nessus Plugin ID 320423

Synopsis

The remote openSUSE host is missing one or more security updates.

Description

The remote openSUSE 16 host has packages installed that are affected by multiple vulnerabilities as referenced in the openSUSE-SU-2026:20907-1 advisory.

 This update for erlang fixes the following issues

 - CVE-2025-4748: improper limitation of a pathname may lead to path traversal (bsc#1244642).
 - CVE-2026-32147: Improper Limitation of a Pathname to a Restricted Directory ('Path Traversal') in SFTP chroot (bsc#1262503).
 - CVE-2026-42789: `public_key` application accepts non-CA certificates as intermediate issuers and this enables chain forgery (bsc#1266449).
 - CVE-2026-42790: Name Constraints and Subject CommonName fallback in TLS hostname verification allows for certificate forgery by MITM attacker (bsc#1266466).
 - CVE-2026-42791: OCSP response verification in the `public_key` application does not check the validity period of the OCSP responder certificate and allows for OCSP response response forgery (bsc#1266448).

Tenable has extracted the preceding description block directly from the SUSE 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

Update the affected packages.
