Several vulnerabilities have been discovered in PHP, a server-side, HTML-embedded scripting language. The Common Vulnerabilities and Exposures project identifies the following problems: Buffer overflow in the imageloadfont function allows a denial of service or code execution through a crafted font file. Buffer overflow in the memnstr function allows a denial of service or code execution via a crafted delimiter parameter to the explode function. Denial of service is possible in the FastCGI module by a remote attacker by making a request with multiple dots before the extension.
