{"id":"UBUNTU-CVE-2024-28834","details":"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 noticeable step in nonce size from 513 to 512 bits, exposing a potential timing side-channel.","modified":"2026-04-22T14:48:08.715612Z","published":"2024-03-21T14:15:00Z","related":["USN-6733-1","USN-6733-2"],"upstream":["CVE-2024-28834"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2024-28834"},{"type":"REPORT","url":"https://lists.gnupg.org/pipermail/gnutls-help/2024-March/004845.html"},{"type":"REPORT","url":"https://www.gnutls.org/security-new.html#GNUTLS-SA-2023-12-04"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/CVE-2024-28834"},{"type":"REPORT","url":"https://people.redhat.com/~hkario/marvin/"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2024-28834"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6733-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-6733-2"}],"affected":[{"package":{"name":"gnutls28","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/gnutls28@3.6.13-2ubuntu1.11?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.6.13-2ubuntu1.11"}]}],"versions":["3.6.9-5ubuntu1","3.6.9-5ubuntu2","3.6.10-5","3.6.11.1-2","3.6.11.1-2ubuntu2","3.6.13-2ubuntu1","3.6.13-2ubuntu1.1","3.6.13-2ubuntu1.2","3.6.13-2ubuntu1.3","3.6.13-2ubuntu1.6","3.6.13-2ubuntu1.7","3.6.13-2ubuntu1.8","3.6.13-2ubuntu1.9","3.6.13-2ubuntu1.10"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"gnutls-bin","binary_version":"3.6.13-2ubuntu1.11"},{"binary_name":"guile-gnutls","binary_version":"3.6.13-2ubuntu1.11"},{"binary_name":"libgnutls-dane0","binary_version":"3.6.13-2ubuntu1.11"},{"binary_name":"libgnutls-openssl27","binary_version":"3.6.13-2ubuntu1.11"},{"binary_name":"libgnutls30","binary_version":"3.6.13-2ubuntu1.11"},{"binary_name":"libgnutlsxx28","binary_version":"3.6.13-2ubuntu1.11"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-28834.json"}},{"package":{"name":"gnutls28","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/gnutls28@3.7.3-4ubuntu1.5?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.7.3-4ubuntu1.5"}]}],"versions":["3.7.1-5ubuntu1","3.7.2-2ubuntu1","3.7.2-4ubuntu1","3.7.2-5ubuntu1","3.7.3-4ubuntu1","3.7.3-4ubuntu1.1","3.7.3-4ubuntu1.2","3.7.3-4ubuntu1.3","3.7.3-4ubuntu1.4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"gnutls-bin","binary_version":"3.7.3-4ubuntu1.5"},{"binary_name":"guile-gnutls","binary_version":"3.7.3-4ubuntu1.5"},{"binary_name":"libgnutls-dane0","binary_version":"3.7.3-4ubuntu1.5"},{"binary_name":"libgnutls-openssl27","binary_version":"3.7.3-4ubuntu1.5"},{"binary_name":"libgnutls30","binary_version":"3.7.3-4ubuntu1.5"},{"binary_version":"3.7.3-4ubuntu1.5","binary_name":"libgnutlsxx28"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-28834.json"}},{"package":{"name":"gnutls28","ecosystem":"Ubuntu:24.04:LTS","purl":"pkg:deb/ubuntu/gnutls28@3.8.3-1.1ubuntu3.1?arch=source&distro=noble"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"3.8.3-1.1ubuntu3.1"}]}],"versions":["3.8.1-4ubuntu1","3.8.1-4ubuntu6","3.8.1-4ubuntu7","3.8.3-1ubuntu1","3.8.3-1.1ubuntu2","3.8.3-1.1ubuntu3"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"gnutls-bin","binary_version":"3.8.3-1.1ubuntu3.1"},{"binary_name":"libgnutls-dane0t64","binary_version":"3.8.3-1.1ubuntu3.1"},{"binary_name":"libgnutls-openssl27t64","binary_version":"3.8.3-1.1ubuntu3.1"},{"binary_name":"libgnutls30t64","binary_version":"3.8.3-1.1ubuntu3.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2024/UBUNTU-CVE-2024-28834.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
