Title
OCSP CertID serial-number length-confusion in wolfSSL_OCSP_resp_find_status
Summary
OCSP CertID serial-number length-confusion in wolfSSL_OCSP_resp_find_status allows a same-issuer SingleResponse whose serial is a prefix of the target serial to be reported as the revocation status of a different certificate. The lookup compared serial-number bytes without first requiring the two serial numbers to be of equal length, so a SingleResponse for one certificate (same issuer) whose serial is a prefix of the target's serial would match, returning the wrong certificate's status. The fix requires the serial lengths to be equal before comparing the serial bytes.

Drag nodes to arrange them. Double-click a related vulnerability to open it, or a source to visit its link. The Physics button on the left tunes the layout and the simulation; the legend at the bottom left hides or shows nodes by kind and by sighting type.

Forecast uses a logistic model when the trend is rising, or an exponential decay model when the trend is falling. Fitted via linearized least squares.
