{"id":"UBUNTU-CVE-2016-2107","details":"The AES-NI implementation in OpenSSL before 1.0.1t and 1.0.2 before 1.0.2h does not consider memory allocation during a certain padding check, which allows remote attackers to obtain sensitive cleartext information via a padding-oracle attack against an AES CBC session. NOTE: this vulnerability exists because of an incorrect fix for CVE-2013-0169.","modified":"2026-04-22T10:36:07.959955Z","published":"2016-05-03T00:00:00Z","related":["USN-2959-1"],"upstream":["CVE-2016-2107"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-2107"},{"type":"REPORT","url":"https://www.openssl.org/news/secadv/20160503.txt"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-2959-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2016-2107"}],"affected":[{"package":{"name":"openssl","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/openssl@1.0.1f-1ubuntu2.19?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.1f-1ubuntu2.19"}]}],"versions":["1.0.1e-3ubuntu1","1.0.1e-4ubuntu1","1.0.1e-4ubuntu2","1.0.1e-4ubuntu3","1.0.1e-4ubuntu4","1.0.1f-1ubuntu1","1.0.1f-1ubuntu2","1.0.1f-1ubuntu2.1","1.0.1f-1ubuntu2.2","1.0.1f-1ubuntu2.3","1.0.1f-1ubuntu2.4","1.0.1f-1ubuntu2.5","1.0.1f-1ubuntu2.7","1.0.1f-1ubuntu2.8","1.0.1f-1ubuntu2.11","1.0.1f-1ubuntu2.12","1.0.1f-1ubuntu2.15","1.0.1f-1ubuntu2.16","1.0.1f-1ubuntu2.17","1.0.1f-1ubuntu2.18"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libssl1.0.0","binary_version":"1.0.1f-1ubuntu2.19"},{"binary_name":"openssl","binary_version":"1.0.1f-1ubuntu2.19"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2016/UBUNTU-CVE-2016-2107.json"}},{"package":{"name":"openssl","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/openssl@1.0.2g-1ubuntu4.1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1.0.2g-1ubuntu4.1"}]}],"versions":["1.0.2d-0ubuntu1","1.0.2d-0ubuntu2","1.0.2e-1ubuntu1","1.0.2f-2ubuntu1","1.0.2g-1ubuntu2","1.0.2g-1ubuntu3","1.0.2g-1ubuntu4"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libssl1.0.0","binary_version":"1.0.2g-1ubuntu4.1"},{"binary_name":"openssl","binary_version":"1.0.2g-1ubuntu4.1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2016/UBUNTU-CVE-2016-2107.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:H/I:N/A:N"},{"type":"Ubuntu","score":"high"}]}
