Detail

A flaw was reported in the TLS session ticket key construction in GnuTLS, a library implementing the TLS and SSL protocols. The flaw caused the TLS server to not securely construct a session ticket encryption key considering the application supplied secret, allowing a man-in-the-middle attacker to bypass authentication in TLS 1.3 and recover previous conversations in TLS 1.2.

For the stable distribution (buster), this problem has been fixed in version 3.6.7-4+deb10u4.

We recommend that you upgrade your gnutls28 packages.
