    webpki: CPU denial of service in certificate path building

    GHSA-8qv2-5vq6-g2g7

    Affected
    • crates.io webpki <= 0.22.1
    Fixed in
    0.22.2· Vendor fix available
    Issue
    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. rustls-webpki is a fork of this crate which contains a fix for this issue and is actively maintained.

    Recommended action: Upgrade to 0.22.2 or later, then redeploy and verify.A vendor fix does not resolve your finding until you verify it in your own systems.
