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
An issue in Netgate pfSense v.2.7.0 allows a remote attacker to execute arbitrary code via a crafted request to the interfaces_gif_edit.php and interfaces_gre_edit.php components.
