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
An unauthenticated, remote attacker could upload malicious logic to the devices based on ProConOS/ProConOS eCLR in order to gain full control over the device.
