DTLS State Information Leakage Vulnerability

CVE-2015-0207 · MEDIUM Severity

AV:N/AC:L/AU:N/C:N/I:N/A:P

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.
