Summary

wbond certvalidator versions 0.11.0 and 0.11.1 are affected. The Certificate Path Builder component does not limit the resources it consumes (CWE-400), so a remote attacker can exhaust resources by manipulating certificate processing. The attack needs no privileges or user interaction, and the vendor did not respond to early disclosure contact.
