Vigil@nce - OpenBSD: denial of service via relayd
December 2014 by Vigil@nce
This bulletin was written by Vigil@nce : http://vigilance.fr/offer
SYNTHESIS OF THE VULNERABILITY
An attacker can send a malicious HTTP packet to the relayd service
of OpenBSD, in order to trigger a denial of service.
Impacted products: OpenBSD
Severity: 2/4
Creation date: 18/11/2014
DESCRIPTION OF THE VULNERABILITY
The relayd service can be installed on OpenBSD.
However, when an HTTP query with a malicious version is received,
a fatal error occurs in the relay_read_http() function.
An attacker can therefore send a malicious HTTP packet to the
relayd service of OpenBSD, in order to trigger a denial of service.
