A fix is available — apply it.

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.
