Am I affected?

With a domain, we read the version its public headers and pages expose. A distribution build can carry the fix under an older number.

Description

SAP Web Dispatcher does not sufficiently validate certain network input processed by an internal component. An unauthenticated attacker could send specially crafted network traffic to trigger a memory corruption condition in the affected functionality. Successful exploitation could allow the attacker to execute arbitrary code and fully compromise the system, resulting in a high impact on confidentiality, integrity and availability of the system.
