OpenSSL is vulnerable to denial of service (DoS) attacks through memory consumption and application crash. This is caused because the dtls1_clear_queues function in d1_lib.c frees data not taking into account that application data could arrive between the ChangeCipherSpec message and the Finished message. This can cause the DTLS peer to buffer the application data and cause a segmentation fault.
