CVE-2022-1343

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. This issue also impacts the command line OpenSSL “ocsp”
application. When verifying an ocsp response with the “-no_cert_checks”
option the command line application will report that the verification is
successful even though it has in fact failed. In this case the incorrect
successful response will also be accompanied by error messages showing the
failure and contradicting the apparently successful result. Fixed in
OpenSSL 3.0.3 (Affected 3.0.0,3.0.1,3.0.2).
