The host is installed with OpenSSL 1.0.1 before 1.0.1k, 1.0.0 before 1.0.0p or 0.9.8 before 0.9.8zd and is prone to a denial of service vulnerability. A flaw is present in the application, which fails to handle a crafted DTLS message that is processed with a different read operation for the handshake header than for the handshake body, related to the dtls1_get_record function in d1_pkt.c and the ssl3_read_n function in s3_pkt.c. Successful exploitation allows remote attackers to cause a denial of service (NULL pointer dereference and application crash).
