| CVE-2024-12243 | Med | 0.35 | 5.3 | 0.01 | Feb 10, 2025 | A flaw was found in GnuTLS, which relies on libtasn1 for ASN.1 data processing. Due to an inefficient algorithm in libtasn1, decoding certain DER-encoded certificate data can take excessive time, leading to increased resource consumption. This flaw allows a remote attacker to… | ||
| CVE-2024-28834 | Med | 0.35 | 5.3 | 0.01 | Mar 21, 2024 | A flaw was found in GnuTLS. The Minerva attack is a cryptographic vulnerability that exploits deterministic behavior in systems like GnuTLS, leading to side-channel leaks. In specific scenarios, such as when using the GNUTLS_PRIVKEY_FLAG_REPRODUCIBLE flag, it can result in a… | ||
