Summary
Francisco Alonso of Red Hat Product Security found an issue in the file utility, whose code is embedded in PHP, a general-purpose scripting language. When checking ELF files, note headers are incorrectly checked, thus potentially allowing attackers to cause a denial of service (out-of-bounds read and application crash) by supplying a specially crafted ELF file.
As announced in DSA-3064-1 it has been decided to follow the stable 5.4.x releases for the Wheezy php5 packages. Consequently the vulnerability is addressed by upgrading PHP to a new upstream version 5.4.35, which includes additional bug fixes, new features and possibly incompatible changes. Please refer to the upstream changelog for more information:
http://php.net/ChangeLog-5.php#5.4.35
Solution
For the stable distribution (wheezy), this problem has been fixed in version 5.4.35-0+deb7u1.
We recommend that you upgrade your php5 packages.
Insight
This package is a metapackage that, when installed, guarantees that you have at least one of the four server-side versions of the PHP5 interpreter installed. Removing this package won't remove PHP5 from your system, however it may remove other packages that depend on this one.
Affected
php5 on Debian Linux
Detection
This check tests the installed software version using the apt package manager.
