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
The monitor barrier of the affected products insufficiently blocks data from being forwarded over the mirror port into the mirrored network. An attacker could use this behavior to transmit malicious packets to systems in the mirrored network, possibly influencing their configuration and runtime behavior.
