Details

It was discovered that GnuTLS had a timing side-channel when processing
malformed ciphertexts in RSA-PSK ClientKeyExchange. A remote attacker could
possibly use this issue to recover sensitive information. (CVE-2024-0553)

It was discovered that GnuTLS incorrectly handled certain certificate
chains with a cross-signing loop. A remote attacker could possibly use this
issue to cause GnuTLS to crash, resulting in a denial of service. This
issue only affected Ubuntu 22.04 LTS, Ubuntu 23.04, and Ubuntu 23.10.
(CVE-2024-0567)
