Gentoo Linux Security Advisory

Title: Motion: Execution of arbitrary code (GLSA 200807-02)
Severity: normal
Exploitable: remote
Date: July 01, 2008
Bug(s): #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: media-video/motion
Vulnerable: < 3.2.10.1
Unaffected: >= 3.2.10.1
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/motion-3.2.10.1"
