WordPress v.2.0.5 Trackback UTF-7 SQL Injection Security Vulnerability

Description
WordPress supports decoding trackbacks with different charsets when PHP's mbstring extension is activated. Because the decoding happens after the database escaping is performed choosing the right charset for the input data allows bypassing the protection against SQL injection.

Confirmed in versions: 2.0.5. Other versions may also be affected.

Impact
The remote attacker can manipulate SQL queries by injecting arbitrary SQL code.
