{"id":"CVE-2016-2183","aliases":["PSF-2016-4"],"url":"https://o3.security/vulnerability/CVE-2016-2183","summary":null,"details":"The DES and Triple DES ciphers, as used in the TLS, SSH, and IPSec protocols and other protocols and products, have a birthday bound of approximately four billion blocks, which makes it easier for remote attackers to obtain cleartext data via a birthday attack against a long-duration encrypted session, as demonstrated by an HTTPS session using Triple DES in CBC mode, aka a \"Sweet32\" attack.","published":"2016-09-01T00:59:00.137Z","modified":"2026-09-13T11:45:12.653884300Z","cvss":{"score":7.5,"severity":"HIGH","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:N/A:N"},"epss":{"score":0.95707,"percentile":0.99868,"asOf":"2026-09-13"},"cisaKev":null,"exploitsKnown":0,"affectedPackages":[],"fix":null,"references":[{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf"},{"type":"WEB","url":"https://www.vicarius.io/vsociety/posts/cve-2016-2183-detection-sweet32-vulnerability"},{"type":"WEB","url":"https://www.vicarius.io/vsociety/posts/cve-2016-2183-mitigate-sweet32-vulnerability"},{"type":"ADVISORY","url":"http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00022.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00023.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00024.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-09/msg00031.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00005.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00011.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00012.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00013.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00021.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2016-10/msg00029.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2017-01/msg00068.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2017-02/msg00003.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2017-02/msg00023.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2017-02/msg00028.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2017-02/msg00032.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2017-05/msg00076.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00010.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2017-10/msg00011.html"},{"type":"ADVISORY","url":"http://lists.opensuse.org/opensuse-security-announce/2018-02/msg00032.html"},{"type":"ADVISORY","url":"http://packetstormsecurity.com/files/142756/IBM-Informix-Dynamic-Server-DLL-Injection-Code-Execution.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2017-0336.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2017-0337.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2017-0338.html"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2017-0462.html"},{"type":"ADVISORY","url":"http://seclists.org/fulldisclosure/2017/Jul/31"},{"type":"ADVISORY","url":"http://seclists.org/fulldisclosure/2017/May/105"},{"type":"ADVISORY","url":"http://www-01.ibm.com/support/docview.wss?uid=nas8N1021697"},{"type":"ADVISORY","url":"http://www-01.ibm.com/support/docview.wss?uid=swg21991482"},{"type":"ADVISORY","url":"http://www-01.ibm.com/support/docview.wss?uid=swg21995039"},{"type":"ADVISORY","url":"http://www.debian.org/security/2016/dsa-3673"},{"type":"ADVISORY","url":"http://www.huawei.com/en/psirt/security-advisories/huawei-sa-20170322-01-openssl-en"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/topics/security/linuxbulletinoct2016-3090545.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/topics/security/ovmbulletinoct2016-3090547.html"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/539885/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/540341/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/541104/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/542005/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/archive/1/539885/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/archive/1/540129/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/archive/1/540341/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/archive/1/541104/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/archive/1/archive/1/542005/100/0/threaded"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/92630"},{"type":"ADVISORY","url":"http://www.securityfocus.com/bid/95568"},{"type":"ADVISORY","url":"http://www.securitytracker.com/id/1036696"},{"t
