Endpoint Vulnerability

Incorrect IDNA domain name matching for wildcard certificates

Description

Security researcher Christian Heimes reported that the Network Security Services (NSS) library does not handle IDNA domain prefixes according to RFC 6125 for wildcard certificates. This leads to improper wildcard matching of domains when they should not be matched in compliance with the specification. This issue was fixed in NSS version 3.16.
