Severity: 3-Major

Symptoms

When a certificate chain is made up of multiple certificates, the verification of the chain may be wrong.

Impact

When the condition matches, the 'SSL::verify_result' may return the wrong result.

Conditions

This happens when the 'untrusted-cert-response-control' and 'expire-cert-response-control' are both set to 'ignore' on server SSL profile, and 'sys db tmm.ssl.servercert_softval' is 'enable'.

Workaround

None.

Fix Information

'SSL::verify_result' returns the correct result.
