OpenSSL < 0.9.8x / < 1.0.0j / < 1.0.1c Remote Denial of Service Vulnerability

OpenSSL before 0.9.8x, 1.0.0.j, or 1.0.1c contains an integer underflow condition which may result in a denial of service. A remote attacker could send a specially crafted TLS request causing the affected application to crash causing denial of service to legitimate users. The integer underflow is seen in TLS 1.1, TLS 1.2, and DTLS when handling CBC mode ciphersuites.
