{"id":"CVE-2016-2179","details":"The DTLS implementation in OpenSSL before 1.1.0 does not properly restrict the lifetime of queue entries associated with unused out-of-order messages, which allows remote attackers to cause a denial of service (memory consumption) by maintaining many crafted DTLS sessions simultaneously, related to d1_lib.c, statem_dtls.c, statem_lib.c, and statem_srvr.c.","modified":"2026-04-16T01:43:03.337022290Z","published":"2016-09-16T05:59:00.143Z","related":["SUSE-FU-2022:0445-1","SUSE-SU-2016:2387-1","SUSE-SU-2016:2394-1","SUSE-SU-2016:2458-1","SUSE-SU-2016:2468-1","SUSE-SU-2016:2469-1","SUSE-SU-2017:2699-1","SUSE-SU-2017:2700-1","openSUSE-SU-2024:10271-1","openSUSE-SU-2024:11127-1"],"references":[{"type":"WEB","url":"http://www.securitytracker.com/id/1036689"},{"type":"WEB","url":"https://cert-portal.siemens.com/productcert/pdf/ssa-412672.pdf"},{"type":"WEB","url":"https://git.openssl.org/?p=openssl.git%3Ba=commit%3Bh=f5c7f5dfbaf0d2f7d946d0fe86f08e6bcb36ed0d"},{"type":"WEB","url":"https://support.hpe.com/hpsc/doc/public/display?docLocale=en_US&docId=emr_na-hpesbhf03856en_us"},{"type":"WEB","url":"https://www.tenable.com/security/tns-2016-20"},{"type":"WEB","url":"https://www.tenable.com/security/tns-2016-21"},{"type":"ADVISORY","url":"http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10759"},{"type":"ADVISORY","url":"http://rhn.redhat.com/errata/RHSA-2016-1940.html"},{"type":"ADVISORY","url":"http://www-01.ibm.com/support/docview.wss?uid=swg21995039"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpuapr2018-3678067.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpujan2018-3236628.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpujul2017-3236622.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpuoct2016-2881722.html"},{"type":"ADVISORY","url":"http://www.oracle.com/technetwork/security-advisory/cpuoct2017-3236626.html"},{"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/bid/92987"},{"type":"ADVISORY","url":"http://www.splunk.com/view/SP-CAAAPSV"},{"type":"ADVISORY","url":"http://www.splunk.com/view/SP-CAAAPUE"},{"type":"ADVISORY","url":"https://bto.bluecoat.com/security-advisory/sa132"},{"type":"ADVISORY","url":"https://kb.pulsesecure.net/articles/Pulse_Security_Advisories/SA40312"},{"type":"ADVISORY","url":"https://security.FreeBSD.org/advisories/FreeBSD-SA-16:26.openssl.asc"},{"type":"ADVISORY","url":"https://www.tenable.com/security/tns-2016-16"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/openssl/openssl","events":[{"introduced":"0"},{"last_affected":"888759a1d38197f29de7227876c3b58fbff8549f"},{"last_affected":"e818b74be2170fbe957a07b0da4401c2b694b3b8"},{"last_affected":"543e15a3c0139e6026ce194f8c8465fb9a559986"},{"last_affected":"fe707c3260cb44f5e7d701cf87e1197712ec7d43"}],"database_specific":{"source":"CPE_FIELD","cpe":["cpe:2.3:a:openssl:openssl:1.0.1:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1a:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1b:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1c:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1d:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1e:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1f:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1g:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1h:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1i:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1j:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1k:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1l:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1m:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1n:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1o:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1p:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1q:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1r:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1s:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.1t:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2a:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2b:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2c:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2d:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2e:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2f:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2g:*:*:*:*:*:*:*","cpe:2.3:a:openssl:openssl:1.0.2h:*:*:*:*:*:*:*","cpe:2.3:o:oracle:linux:6:*:*:*:*:*:*:*","cpe:2.3:o:oracle:linux:7:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"0"},{"last_affected":"1.0.1"},{"last_affected":"1.0.1a"},{"last_affected":"1.0.1b"},{"last_affected":"1.0.1c"},{"last_affected":"1.0.1d"},{"last_affected":"1.0.1e"},{"last_affected":"1.0.1f"},{"last_affected":"1.0.1g"},{"last_affected":"1.0.1h"},{"last_affected":"1.0.1i"},{"last_affected":"1.0.1j"},{"last_affected":"1.0.1k"},{"last_affected":"1.0.1l"},{"last_affected":"1.0.1m"},{"last_affected":"1.0.1n"},{"last_affected":"1.0.1o"},{"last_affected":"1.0.1p"},{"last_affected":"1.0.1q"},{"last_affected":"1.0.1r"},{"last_affected":"1.0.1s"},{"last_affected":"1.0.1t"},{"last_affected":"1.
