{"id":"UBUNTU-CVE-2017-14737","details":"A cryptographic cache-based side channel in the RSA implementation in Botan before 1.10.17, and 1.11.x and 2.x before 2.3.0, allows a local attacker to recover information about RSA secret keys, as demonstrated by CacheD. This occurs because an array is indexed with bits derived from a secret key.","modified":"2026-04-22T11:16:16.872074Z","published":"2017-09-26T01:29:00Z","upstream":["CVE-2017-14737"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-14737"},{"type":"REPORT","url":"https://github.com/randombit/botan/issues/1222"},{"type":"REPORT","url":"https://www.usenix.org/conference/usenixsecurity17/technical-sessions/presentation/wang-shuai"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-14737"}],"affected":[{"package":{"name":"botan1.10","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/botan1.10@1.10.5-1+deb7u1ubuntu0.14.04.1+esm1?arch=source&distro=trusty/esm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.10.5-1+deb7u1ubuntu0.14.04.1+esm1"}]}],"versions":["1.10.5-1","1.10.5-1ubuntu1","1.10.5-1+deb7u1ubuntu0.14.04.1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro","binaries":[{"binary_name":"libbotan-1.10-0","binary_version":"1.10.5-1+deb7u1ubuntu0.14.04.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-14737.json"}},{"package":{"name":"botan1.10","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/botan1.10@1.10.12-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.10.10-6","1.10.12-1"],"ecosystem_specific":{"binaries":[{"binary_name":"libbotan-1.10-1","binary_version":"1.10.12-1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-14737.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"medium"}]}
