The ephemeral ECDH ciphersuite functionality in OpenSSL 0.9.8 through 0.9.8r and 1.0.x before 1.0.0e does not ensure thread safety during processing of handshake messages from clients, which allows remote attackers to cause a denial of service (daemon crash) via out-of-order messages that violate the TLS protocol.
The issue has been introduced in 07/05/2005. The weakness was disclosed 09/22/2011 (Website). The advisory is shared for download at cvs.openssl.org. This vulnerability is handled as CVE-2011-3210. The exploitation is known to be easy. The attack may be launched remotely. No form of authentication is required for exploitation. There are neither technical details nor an exploit publicly available. The current price for an exploit might be approx. USD $0-$5k (estimation calculated on 08/06/2024).
The vulnerability was handled as a non-public zero-day exploit for at least 2270 days. During that time the estimated underground price was around $5k-$25k.
