PHP imagepsloadfont buffer overflow
| php-imagepsloadfont-bo (35620) |  High Risk |
Description:
PHP is vulnerable to a buffer overflow, caused by improper bounds checking by the imagepsloadfont function. By sending a specially-crafted request, a remote attacker could overflow a buffer and execute arbitrary code on the system.
Note: In order to exploit this vulnerability, the GD (php_gd2.dll) extension for PHP must be enabled.
