Details
It was discovered that GnuTLS had a timing side-channel when performing certain ECDSA operations. A remote attacker could possibly use this issue to recover sensitive information. (CVE-2024-28834)
It was discovered that GnuTLS incorrectly handled verifying certain PEM bundles. 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 and Ubuntu 23.10. (CVE-2024-28835)
