CVE-2015-0207 is a vulnerability of currently unknown severity. The dtls1_listen function in d1_lib.c in OpenSSL 1.0.2 before 1.0.2a does not properly isolate the state information of independent data streams, which allows remote attackers to cause a denial of service (application crash) via crafted DTLS traffic, as demonstrated by DTLS 1.0 traffic to a DTLS 1.2 server.. EPSS estimates a 7.35% chance of exploitation in the next 30 days.
