GLSA 200807-02: Motion: Execution of arbitrary code

http://security.gentoo.org/

Severity:	normal
Title:	Motion: Execution of arbitrary code
Date:	07/01/2008
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	Architecture(s)
media-video/motion	< 3.2.10.1	>= 3.2.10.1	All supported architectures

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"
