NVD Description

Note: Versions mentioned in the description apply only to the upstream gnutls28 package and not the gnutls28 package as distributed by Debian. See How to fix? for Debian:12 relevant fixed versions and status.

A flaw was found in GnuTLS. The gnutls_pkcs11_token_set_pin function, used for changing the Security Officer PIN, can lead to a use-after-free vulnerability. This occurs when an attacker attempts to change the PIN with a NULL old PIN for a token that lacks a protected authentication path.
