Description

It was discovered that PHP5 was vulnerable to a reflected cross-site scripting (XSS) attack on the PHAR 404 error page by manipulating the URI of a request for a .phar file. This issue is only exploitable if the web server is configured to handle phar files using PHP5.

For Debian 7 'Wheezy', these problems have been fixed in version 5.4.45-0+deb7u12.

We recommend that you upgrade your php5 packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
