|Gentoo Linux Security Advisory
Title: Motion: Execution of arbitrary code (GLSA 200807-02)
Date: July 01, 2008
Multiple vulnerabilities in Motion might result in the execution of arbitrary code.
Motion is a program that monitors the video signal from one or more cameras and is able to detect motions.
Vulnerable: < 22.214.171.124
Unaffected: >= 126.96.36.199
Architectures: All supported architectures
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.
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.
There is no known workaround at this time.
All Motion users should upgrade to the latest version:
|# emerge --sync
# emerge --ask --oneshot --verbose ">=media-video/motion-188.8.131.52"
