CVE-2009-3046
Opera before 10.00 does not check all intermediate X.509 certificates for revocation, which makes it easier for remote SSL servers to bypass validation of the certificate chain via a revoked certificate.
Does this matter?
High impact if exploited, but EPSS currently rates exploitation as unlikely (1.11%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.
