FreeBSD : GnuTLS -- flaw in TLS session ticket key construction (ef5b4f5f-a658-11ea-80d7-001cc0382b2f)

The GnuTLS project reports : It was found that GnuTLS 3.6.4 introduced a regression in the TLS protocol implementation. This caused the TLS server to not securely construct a session ticket encryption key considering the application supplied secret, allowing a MitM attacker to bypass authenticati...

GnuTLS Encryption Problem Vulnerability (CNVD-2020-53541)

GnuTLS is a free secure communication library for implementing SSL, TLS and DTLS protocols. A security vulnerability exists in GnuTLS version 3.6.14. An attacker can exploit this vulnerability by performing a man-in-the-middle attack to bypass authentication in TLS version 1.3 and recover previou...
