Description

PHP contains a flaw that may allow an attacker to create a denial of service condition. The issue is due to the array_fill() function filling arrays with 'num' entries unsafely. If an attacker sets a large 'num' value it may exhaust all available system memory and make the system unsable if the 'memory_limit' option in php.ini is set high.
