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
Instruments with Illumina Universal Copy Service v1.x and v2.x contain an unnecessary privileges vulnerability. An unauthenticated malicious actor could upload and execute code remotely at the operating system level, which could allow an attacker to change settings, configurations, software, or access sensitive data on the affected product.
