This is a Service Pack release of the MySQL Enterprise Server 5.0.
This is a bugfix release that replaces MySQL 5.0.50sp1.
Security Fix: Three vulnerabilities in yaSSL versions 1.7.5 and earlier were discovered that could lead to a server crash or execution of unauthorized code. The exploit requires a server with yaSSL enabled and TCP/IP connections enabled, but does not require valid MySQL account credentials. The exploit does not apply to OpenSSL.
The proof-of-concept exploit is freely available on the Internet. Everyone with a vulnerable MySQL configuration is advised to upgrade immediately.
