CVE-2015-4026

Name of the Vulnerable Software and Affected Versions PHP versions prior to 5.4.41 PHP versions 5.5.x prior to 5.5.25 PHP versions 5.6.x prior to 5.6.9

Description The issue is related to the pcntl exec implementation in PHP, which incorrectly handles pathnames containing a x00 character. This might allow remote attackers to bypass security restrictions and execute files with unexpected names by providing a crafted first argument. The problem arises from an incomplete fix for a previous issue.

Recommendations For PHP versions prior to 5.4.41, update to version 5.4.41 or later. For PHP versions 5.5.x prior to 5.5.25, update to version 5.5.25 or later. For PHP versions 5.6.x prior to 5.6.9, update to version 5.6.9 or later.
