Christey" <coley@...us.mitre.org> Cc: Andrey Petrov <andrey.petrov@...zow.net>, Jamie Strandboge <jamie@...ntu.com>, oss-security@...ts.openwall.com Subject: Re: CVE Request -- urllib3: Does not check for SSL certificates by default Steve, in relation to this one the following question has been raised internally - it's OK to assign CVE identifier for end user applications, proclaiming to perform SSL certificates verification, but not doing that. But what about the libraries? Obviously urllib3 when instructed to do so, performs the verification. The question is should it get a CVE identifier or not? Could you clarify Mitre's opinion / view on this?
