Overview
Affected versions of this package are vulnerable to Buffer Over-read due to the improper configuration of SSLContext.set_npn_protocols. An attacker can configure an empty list as a value for NPN protocols.
Note: This vulnerability is of low severity due to NPN being not widely used and specifying an empty list likely being uncommon in-practice, typically a protocol name would be configured.
