Detailed vulnerability description

The vulnerability allows a remote attacker to perform MitM attack.

The vulnerability exists due to an error in fetch(1) when handling certificate revocation file passed via the "--crl" option. The environment variable name used by fetch(1) to pass the filename to the library was incorrect, in effect ignoring the option. As a result, the library will still connect to a host presenting a certificate that was included into the revocation list.
