Am I affected?
Debian, Ubuntu or Red Hat sometimes backport a fix without changing the upstream version number: such a version reads « to verify », never « 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
The length of the input fields of Host Engineering H0-ECOM100, H2-ECOM100, and H4-ECOM100 modules are verified only on the client side when receiving input from the configuration web server, which may allow an attacker to bypass the check and send input to crash the device.
