4) Description of Vulnerability
Secunia Research has discovered a vulnerability in Motion, which can
be exploited by malicious people to compromise a vulnerable system.
The vulnerability is caused due to a boundary error within
the "read_client()" function in webhttpd.c. This can be exploited to
cause a stack-based buffer overflow by sending a specially crafted
request to the HTTP control interface.
Successful exploitation allows execution of arbitrary code, but
requires that the Motion HTTP control interface is enabled.

5) Solution
Update to version 3.2.10.1.
