Disclaimer: Community trackers are created by Red Hat Product Security team on a best effort basis. Package maintainers are required to ascertain if the flaw indeed affects their package, before starting the update process. rustls-webpki (rustls/webpki) versions 0.101.0 through 0.103.11 and 0.104.0-alpha releases before 0.104.0-alpha.6 ignore X.509 name constraints that apply to URI names, causing such constraints to be accepted rather than enforced. Because name constraints are restrictions on otherwise properly issued certificates, the flaw is only reachable after successful signature verification and requires a misissued certificate to exploit; the library also provides no API for asserting URI names, and URI name constraints are otherwise unimplemented. Versions 0.103.12 and 0.104.0-alpha.6 reject URI name constraints unconditionally.
The rust-rustls-webpki package was updated to 0.103.13 around six months ago, and the uv package has been updated in all branches (and therefore rebuilt with the latest packaged rustls-webpki) many times since then. Even in EPEL10.2, the last update was four months ago. (The uv package generally stops getting updates in a new EPEL10 minor-version branch almost immediately due to the ban on updating Rust libraries across SemVer boundaries in non-leading EPEL branches.)
