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"
