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
Authorized users may install a maliciously modified package file when updating the device via the web user interface. The user may inadvertently use a package file obtained from an unauthorized source or a file that was compromised between download and deployment.
