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...

Denial Of Service (DoS)

gnutls is vulnerable to Denial Of Service DoS. A flaw was found in the way GnuTLS decrypted malformed TLS records. This could cause a TLS/SSL client or server to crash when processing a specially-crafted TLS record from a remote TLS/SSL connection peer...

Denial Of Service (DoS)

gnutls is vulnerable to Denial Of Service DoS. A flaw was found in the way libtasn1 decoded DER data. An attacker could create a carefully-crafted X.509 certificate that, when parsed by an application that uses GnuTLS, could cause the application to crash...

Denial Of Service (DoS)

gnutls is vulnerable to denial of service. A boundary error was found in the gnutlssessiongetdata function. A malicious TLS/SSL server could use this flaw to crash a TLS/SSL client or, possibly, execute arbitrary code as the client, if the client passed a fixed-sized buffer to gnutlssessiongetdat...
