Synopsis
=======
A vulnerability in Motion allows a remote attacker to cause denial of
service.

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 < 4.3.2 >= 4.3.2

Description
==========
The Motion HTTP server does not correctly perform URL decoding. If the
HTTP server receives a request for a URL containing an incomplete
percent-encoded character, a flaw in parsing results in an infinite loop
trying to parse the rest of the character, which eventually results in a
denial of service condition when reading out-of-bounds.

Impact
=====
A remote attacker can trigger a denial of service condition in Motion.

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-4.3.2"
