Synopsis

========

 

Multiple vulnerabilities in Motion might result in the execution of

arbitrary code.

 

Background

==========

 

Motion is a program that monitors the video signal from one or more

cameras and is able to detect motions.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 media-video/motion < 3.2.10.1 >= 3.2.10.1

 

Description

===========

 

Nico Golde reported an off-by-one error within the read_client()

function in the webhttpd.c file, leading to a stack-based buffer

overflow. Stefan Cornelius (Secunia Research) reported a boundary error

within the same function, also leading to a stack-based buffer

overflow. Both vulnerabilities require that the HTTP Control interface

is enabled.

 

Impact

======

 

A remote attacker could exploit these vulnerabilities by sending an

overly long or specially crafted request to a vulnerable Motion HTTP

control interface, possibly resulting in the execution of arbitrary

code with the privileges of the motion user.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All Motion users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=media-video/motion-3.2.10.1"
