According to the SecurityFocus newsletter (#238), there are a few vulnerabilities in some qidely used PHP applications you just might need to worry about.

Via Daniel Convissor from NYPHP Talk, are pointers to the latest security vulnerabilities from SecurityFocus:

• phpNewsManager Functions Script File Disclosure Vulnerability
• XMB Forum Multiple Input Validation Vulnerabilities
• Opt-X header.php Remote File Include Vulnerability

Some of the "gotchas" mentioned above are pretty benign, but don't let that fool you. In the wrong hands, even a simple little bug can make your site come crashing down... many thanks to PHP Magazine for the pointer.
