As detailed on the WashPo link, it's a notable policy shift that NSA did
the public-spirited thing with this discovery and, first, conveyed
details of this huge, critical flaw in Microsoft Windows CryptoAPI
(Crypt32.dll library), and then issued a public CVE.
The National Security Agency recently discovered a major flaw in
Microsoft’s Windows operating system — one that could expose computer
users to significant breaches, surveillance or disruption — and alerted
the firm about the problem rather than turning it into a hacking weapon,
officials announced Tuesday.
The public disclosure represents a major shift in the NSA’s approach,
choosing to put computer security ahead of building up its arsenal of
hacking tools that allow the agency to spy on adversaries’ networks.
“This is . . . a change in approach . . . by NSA of working to share,
working to lean forward and then working to really share the data as
part of building trust,” said Anne Neuberger, director of the NSA’s
Cybersecurity Directorate, which was launched in October. “As soon as we
learned about [the flaw], we turned it over to Microsoft.”
