Multiple security vulnerabilities have been discovered in GnuTLS, a library implementing the TLS and SSL protocols, which may result in execution of arbitrary code, denial of service, information leak, certificate misuse, name constraint bypass, authentication bypass, revocation bypass or timing side-channel attacks.

For the oldstable distribution (bookworm), these problems have been fixed in version 3.7.9-2+deb12u7.
