Please don't merge this.

This is 1) a degredation of functionality, 2) improperly formatted, and 3) completely wrong.

I even wonder if @asvd was even notified of anything remotely related to this CVE before it was filed. If not, then whomever filed it should be fired from their job if it was done on behalf of a security company.

In an effort to fight back against the mockery that has become the CVE system I've filed a correction to this CVE here: github/advisory-database#5730

If the author of this CVE is reading, please do better in the future.

Also why is one faceless user the author of the commit but another similarly named faceless user the author of the PR? What is happening here? It reeks of fraud.
