Debian DSA-2868-1 : php5 - denial of service

Medium Nessus Plugin ID 72758

Synopsis

The remote Debian host is missing a security-related update.

Description

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.

Solution

Upgrade the php5 packages.

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.
