Template for a VuXML entry
Check the version numbers before you commit this entry. Some ports share an entry in the CVE database with another port, such as sqlite2 and sqlite3. The version shown here may then be one that never existed for this port.
Not finished: this entry still needs a checked upper bound for every package. Do not commit it as it is.
Ranges per package from the CVE rows that match this port, in pkg notation with the port's epoch and revision, every bound checked with pkg; one range per epoch the port actually had. make newentry in security/vuxml creates the vid.
devel/qt5 (CPE taken from Repology) has no USES=cpe. The CVE was matched through a CPE from another source, so the package and the version range may belong to a different product. Check the CVE record before using this entry.
