PHP multipart/form-data POST handler buffer overflow
|php-multipart-handler-bo (9635)||High Risk|
PHP is vulnerable to a buffer overflow in the multipart/form-data handler code, which could allow a remote attacker to gain control over an affected Web server or cause a denial of service attack. By sending a malformed HTTP POST request, a remote attacker could overflow a buffer and execute arbitrary code on the Web server or possibly cause the Web server to crash.
