Summary

webpki: CPU denial of service in certificate path building

Details

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 and re-reported recently by Luke Malinowski.

webpki 0.22.1 included a partial fix and webpki 0.22.2 added further fixes.

CVE-2018-16875 (GCVE-0-2018-16875)

Vulnerability from cvelistv5 – Published: 2018-12-14 14:00 – Updated: 2024-08-05 10:32

Summary

The crypto/x509 package of Go before 1.10.6 and 1.11.x before 1.11.3 does not limit the amount of work performed for each chain verification, which might allow attackers to craft pathological inputs leading to a CPU denial of service. Go TLS servers accepting client certificates and TLS clients are affected.

Severity ?

5.9 (Medium)

Vulnerability from github – Published: 2023-08-25 00:12 – Updated: 2023-09-06 17:36

Summary

webpki: CPU denial of service in certificate path building

Details

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.

Severity ?

7.5 (High)
