Description

Dräger Perseus A500 software versions 2.00 through 2.02 contains an improper input handling vulnerability that allows external attackers to cause a denial of service by sending specifically crafted non-Medibus-compliant data through the Medibus interface. Attackers can overload the internal processor with malformed data to trigger a warm restart, causing ventilation pressure to drop to ambient level and interrupting ventilation for several seconds before therapy resumes.
