{"id":"UBUNTU-CVE-2016-2183","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.","modified":"2026-04-22T11:01:30.648425Z","published":"2016-08-31T00:00:00Z","related":["USN-3087-1","USN-3179-1","USN-3194-1","USN-3198-1","USN-3270-1","USN-3372-1"],"upstream":["CVE-2016-2183"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2016-2183"},{"type":"REPORT","url":"https://sweet32.info/"},{"type":"REPORT","url":"https://access.redhat.com/articles/2548661"},{"type":"REPORT","url":"https://access.redhat.com/security/cve/cve-2016-2183"},{"type":"REPORT","url":"https://blog.cryptographyengineering.com/2016/08/24/attack-of-week-64-bit-ciphers-in-tls/"},{"type":"REPORT","url":"https://community.qualys.com/thread/16555"},{"type":"REPORT","url":"https://github.com/ssllabs/ssllabs-scan/issues/387#issuecomment-242514633"},{"type":"REPORT","url":"https://nakedsecurity.sophos.com/2016/08/25/anatomy-of-a-cryptographic-collision-the-sweet32-attack/"},{"type":"REPORT","url":"https://quickview.cloudapps.cisco.com/quickview/bug/CSCvb05575"},{"type":"REPORT","url":"https://security-tracker.debian.org/tracker/CVE-2016-2183"},{"type":"REPORT","url":"https://twitter.com/symantec/status/768786631159603200"},{"type":"REPORT","url":"https://www.ietf.org/mail-archive/web/tls/current/msg04560.html"},{"type":"REPORT","url":"https://www.nccgroup.trust/us/about-us/newsroom-and-events/blog/2016/august/new-practical-attacks-on-64-bit-block-ciphers-3des-blowfish/"},{"type":"REPORT","url":"https://www.openssl.org/blog/blog/2016/08/24/sweet32/"},{"type":"REPORT","url":"https://www.sigsac.org/ccs/CCS2016/accepted-papers/"},{"type":"REPORT","url":"https://www.suse.com/security/cve/CVE-2016-2183.html"},{"type":"REPORT","url":"https://www.teskalabs.com/blog/teskalabs-bulletin-160826-seacat-sweet32-issue"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3087-1"},{"type":"REPORT","url":"http://hg.openjdk.java.net/jdk8u/jdk8u/jdk/rev/5d2bb853ae31"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3179-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3194-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3198-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3270-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-3372-1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2016-2183"}],"affected":[{"package":{"name":"nss","ecosystem":"Ubuntu:14.04:LTS","purl":"pkg:deb/ubuntu/nss@2:3.28.4-0ubuntu0.14.04.1?arch=source&distro=trusty"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:3.28.4-0ubuntu0.14.04.1"}]}],"versions":["2:3.15.1-1ubuntu1","2:3.15.2-1","2:3.15.3-1","2:3.15.3.1-1","2:3.15.3.1-1.1","2:3.15.3.1-1.1ubuntu1","2:3.15.4-1ubuntu3","2:3.15.4-1ubuntu4","2:3.15.4-1ubuntu5","2:3.15.4-1ubuntu6","2:3.15.4-1ubuntu7","2:3.15.4-1ubuntu7.1","2:3.17-0ubuntu0.14.04.1","2:3.17.1-0ubuntu0.14.04.1","2:3.17.1-0ubuntu0.14.04.2","2:3.17.4-0ubuntu0.14.04.1","2:3.19.2-0ubuntu0.14.04.1","2:3.19.2.1-0ubuntu0.14.04.1","2:3.19.2.1-0ubuntu0.14.04.2","2:3.21-0ubuntu0.14.04.1","2:3.21-0ubuntu0.14.04.2","2:3.23-0ubuntu0.14.04.1","2:3.26.2-0ubuntu0.14.04.3"],"ecosystem_specific":{"availability":"No
