Firefly Media Server ws_getpostvars buffer overflow
| firefly-wsgetpostvars-bo (41850) |  High Risk |
Description:
Firefly Media Server is vulnerable to a heap-based buffer overflow, caused by an integer overflow error in the ws_getpostvars function. By sending a specially-crafted HTTP POST request containing an overly large Content-Length value, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
