Summary

`OCSP_basic_verify` may incorrectly verify the response signing certificate

Details

The function OCSP_basic_verify verifies the signer certificate on an OCSP response. In the case where the (non-default) flag OCSP_NOCHECKS is used then the response will be positive (meaning a successful verification) even in the case where the response signing certificate fails to verify.

It is anticipated that most users of OCSP_basic_verify will not use the OCSP_NOCHECKS flag. In this case the OCSP_basic_verify function will return a negative value (indicating a fatal error) in the case of a certificate verification failure. The normal expected return value in this case would be 0.
