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
A vulnerability has been identified in Automation License Manager 5 (All versions < 5.3.4.4), Automation License Manager 6 (All versions < 6.0.1). A directory traversal vulnerability could allow a remote attacker to move arbitrary files, which can result in code execution, compromising confidentiality, integrity and availability of the system. Successful exploitation requires a network connection to the affected device. The attacker does not need privileges or special conditions of the system, but user interaction is required.
