Multiple security issues were found in PHP, a widely-used open source general purpose scripting language: The EXIF module was susceptible to denial of service/information disclosure when parsing malformed images, the Apache module allowed cross-site-scripting via the body of a ‘Transfer-Encoding: chunked’ request and the IMAP extension performed insufficient input validation which can result in the execution of arbitrary shell commands in the imap_open() function and denial of service in the imap_mail() function.
