webpki: CPU denial of service in certificate path building

Details
Package webpki
Version 0.22.0
Date 2023-08-22

When this crate is given a pathological certificate chain to validate, it will spend CPU time exponential with the number of candidate certificates at each step of path building.

Both TLS clients and TLS servers that accept client certificate are affected.

This was previously reported in <https://github.com/briansmith/webpki/issues/69&gt; and re-reported recently by Luke Malinowski.

rustls-webpki is a fork of this crate which contains a fix for this issue and is actively maintained.

See advisory page for additional details.
