Gentoo Linux Security Advisory GLSA 200807-02 - 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. Versions less than 3.2.10.1 are affected.

Severity: Normal
Title: Motion: Execution of arbitrary code
Date: July 01, 2008
Bugs: #227053
ID: 200807-02

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"
