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
ARC Informatique PcVue prior to version 12.0.17 is vulnerable due to the deserialization of untrusted data, which may allow an attacker to remotely execute arbitrary code on the web and mobile back-end server.
