Name of the Vulnerable Software and Affected Versions Dräger Perseus A500 versions 2.00 through 2.02

Description Improper input handling allows external attackers to cause a denial of service by sending specifically crafted non-Medibus-compliant data through the Medibus interface. This can overload the internal processor with malformed data, triggering a warm restart. Consequently, ventilation pressure drops to ambient level, interrupting ventilation for several seconds before therapy resumes.
