It was discovered that file, a file type classification tool, contains a flaw in the handling of indirect magic rules in the libmagic library, which leads to an infinite recursion when trying to determine the file type of certain files. The Common Vulnerabilities and Exposures project ID CVE-2014-1943 has been assigned to identify this flaw. Additionally, other well-crafted files might result in long computation times (while using 100% CPU) and overlong results. This update corrects this flaw in the copy that is embedded in the php5 package.

For the oldstable distribution (squeeze), this problem has been fixed in version 5.3.3-7+squeeze19. For the stable distribution (wheezy), this problem has been fixed in version 5.4.4-14+deb7u8. For the testing distribution (jessie) and the unstable distribution (sid), this problem will be fixed soon. We recommend that you upgrade your php5 packages.

This package is a metapackage that, when installed, guarantees that you have at least one of the three 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.
