Authentication flaw

wolfSSL prior to 5.6.6 did not check that messages in one DTLS record do not span key boundaries. As a result, it was possible to combine DTLS messages using different keys into one DTLS record. The most extreme edge case is that, in DTLS 1.3, it was possible that an unencrypted DTLS 1.3 record...

CVE-2023-6937

Summary: CVE-2023-6937 affects wolfSSL prior to 5.6.6, where messages within a single (D)TLS record were not checked for crossing key boundaries. This allows combining messages encrypted under different keys into one record, with a notable edge case in (D)TLS 1.3 where an unencrypted server fligh...

gnutls: incomplete fix for CVE-2023-5981

A vulnerability was found in GnuTLS. The response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from the response times of ciphertexts with correct PKCS1 v1.5 padding. This issue may allow a remote attacker to perform a timing side-channel attack in the RSA-PSK key exchange,...
