Eric Biggers 29e76b211e PKCS#7: fix certificate blacklisting ...

commit 29f4a67c17e19314b7d74b8569be935e6c7edf50 upstream.

If there is a blacklisted certificate in a SignerInfo's certificate
chain, then pkcs7_verify_sig_chain() sets sinfo->blacklisted and returns
0.  But, pkcs7_verify() fails to handle this case appropriately, as it
actually continues on to the line 'actual_ret = 0;', indicating that the
SignerInfo has passed verification.  Consequently, PKCS#7 signature
verification ignores the certificate blacklist.

Fix this by not considering blacklisted SignerInfos to have passed
verification.

Also fix the function comment with regards to when 0 is returned.

Fixes: 03bb79315ddc ("PKCS#7: Handle blacklisted certificates")
