Miggo AIRoot Cause Analysis

The advisory explicitly identifies RawCertParser as the vulnerable component and describes an infinite loop condition during certificate parsing. The 'next' method in Rust iterators is typically responsible for advancing through elements. The described vulnerability pattern matches a faulty iterator implementation that doesn't properly consume input bytes when encountering errors, leading to reprocessing the same data. The introduction of a specific error type (cert::raw::Error::UnuspportedCert) in the fix suggests the loop logic was modified to handle this case and advance the stream appropriately.
