OpenSSL DTLS buffered message DoS (CVE-2016-2179)

Severity CVSS Published Added Modified
5 (AV:N/AC:L/Au:N/C:N/I:N/A:P) September 15, 2016 September 22, 2016 October 29, 2017

Description

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.
