[ GLSA 200807-02 ] Motion: Execution of arbitrary code

[GLSA]

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:
