PHP is prone to multiple vulnerabilities that permit an attacker to bypass the 'safedir' directory restriction. An attacker can exploit these vulnerabilities to possible execute arbitrary code currently existing on a vulnerable system, or to retrieve the contents of arbitrary files, all in the security context of the Web server process.
Affected PHP version 5.5.0.
Upgrade PHP to the latest version.
