{"id":"UBUNTU-CVE-2022-29242","details":"GOST engine is a reference implementation of the Russian GOST crypto algorithms for OpenSSL. TLS clients using GOST engine when ciphersuite `TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC` is agreed and the server uses 512 bit GOST secret keys are vulnerable to buffer overflow. GOST engine version 3.0.1 contains a patch for this issue. Disabling ciphersuite `TLS_GOSTR341112_256_WITH_KUZNYECHIK_CTR_OMAC` is a possible workaround.","modified":"2025-10-24T04:53:38Z","published":"2022-05-24T15:15:00Z","upstream":["CVE-2022-29242"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2022-29242"},{"type":"REPORT","url":"https://github.com/gost-engine/engine/commit/b2b4d629f100eaee9f5942a106b1ccefe85b8808"},{"type":"REPORT","url":"https://github.com/gost-engine/engine/releases/tag/v3.0.1"},{"type":"REPORT","url":"https://github.com/gost-engine/engine/commit/7df766124f87768b43b9e8947c5a01e17545772c"},{"type":"REPORT","url":"https://github.com/gost-engine/engine/commit/c6655a0b620a3e31f085cc906f8073fe81b2fad3"},{"type":"REPORT","url":"https://github.com/gost-engine/engine/security/advisories/GHSA-2rmw-8wpg-vgw5"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2022-29242"}],"affected":[{"package":{"name":"libengine-gost-openssl1.1","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/libengine-gost-openssl1.1@1.1.0.1-1?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0.1-1"],"ecosystem_specific":{"binaries":[{"binary_name":"gostsum","binary_version":"1.1.0.1-1"},{"binary_name":"libengine-gost-openssl1.1","binary_version":"1.1.0.1-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-29242.json"}},{"package":{"name":"libengine-gost-openssl1.1","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/libengine-gost-openssl1.1@1.1.0.3-1?arch=source&distro=focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0.3-1"],"ecosystem_specific":{"binaries":[{"binary_name":"gostsum","binary_version":"1.1.0.3-1"},{"binary_name":"libengine-gost-openssl1.1","binary_version":"1.1.0.3-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-29242.json"}},{"package":{"name":"libengine-gost-openssl1.1","ecosystem":"Ubuntu:22.04:LTS","purl":"pkg:deb/ubuntu/libengine-gost-openssl1.1@1.1.0.3-1ubuntu1?arch=source&distro=jammy"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.1.0.3-1","1.1.0.3-1ubuntu1"],"ecosystem_specific":{"binaries":[{"binary_name":"gostsum","binary_version":"1.1.0.3-1ubuntu1"},{"binary_name":"libengine-gost-openssl1.1","binary_version":"1.1.0.3-1ubuntu1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2022/UBUNTU-CVE-2022-29242.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H"},{"type":"Ubuntu","score":"medium"}]}
