Motion read_client function buffer overflow
| motion-readclient-bo (42979) |  High Risk |
Description:
Motion is vulnerable to a stack-based buffer overflow, caused by an off-by-one error in the read_client function when the HTTP control interface is enabled. By sending an overly long request to the HTTP control interface, a remote attacker could overflow a buffer and execute arbitrary code on the system with elevated privileges or cause the application to crash.
