This fixes a couple CVEs:
** libgnutls: Fix NULL pointer dereference in PSK binder verification A TLS 1.3 resumption attempt with an invalid PSK binder value in ClientHello could lead to a denial of service attack via crashing the server. The updated code guards against the problematic dereference. Reported by Jaehun Lee. [Fixes: GNUTLS-SA-2026-02-09-1, CVSS: high] [CVE-2026-1584]
** libgnutls: Fix name constraint processing performance issue Verifying certificates with pathological amounts of name constraints could lead to a denial of service attack via resource exhaustion. Reworked processing algorithms exhibit better performance characteristics. Reported by Tim Scheckenbach. [Fixes: GNUTLS-SA-2026-02-09-2, CVSS: medium] [CVE-2025-14831]
