An update that solves five vulnerabilities can now be installed.

## Description:

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).
