PHP is an open source general-purpose scripting language that is especially suited for web development.
It was discovered that PHP did not properly handle PHAR files.
A remote attacker could entice a user to open a specially crafted PHAR file using PHP, possibly allowing attacker to obtain sensitive information or cause a Denial of Service condition.
There is no known workaround at this time.
