| CVE-2023-5981 | 3 Fedoraproject, Gnu, Redhat | 3 Fedora, Gnutls, Linux | 2024-01-10 | N/A | 5.9 MEDIUM |
| A vulnerability was found that the response times to malformed ciphertexts in RSA-PSK ClientKeyExchange differ from response times of ciphertexts with correct PKCS#1 v1.5 padding. | |||||
| CVE-2020-11501 | 5 Canonical, Debian, Fedoraproject and 2 more | 5 Ubuntu Linux, Debian Linux, Fedora and 2 more | 2021-07-21 | 5.8 MEDIUM | 7.4 HIGH |
| GnuTLS 3.6.x before 3.6.13 uses incorrect cryptography for DTLS. The earliest affected version is 3.6.3 (2018-07-16) because of an error in a 2017-10-06 commit.
