The vulnerability of the implementation of the HMAC-SHA-384 mechanism in the GnuTLS cryptographic library allows a perpetrator to carry out an “Lucky 13” attack and a attack that recovers the plaintext.

The vulnerability of the implementation of the HMAC-SHA-384 mechanism in the GnuTLS cryptographic library is related to errors in the implementation of the cryptographic algorithm. Exploiting this vulnerability allows a malicious actor to perform both a “Lucky 13” attack and an attack that recove...
