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.

In Bouncy Castle for Java before 1.85, OER parser recurses without depth limit on self-referential IEEE 1609.2 schema. This issue also affects Bouncy Castle for Java LTS before 2.73.12, and Bouncy Castle for Java FIPS (BC-FJA) before bcutil-fips 2.0.7 (2.0.X series) and 2.1.7 (2.1.X series).
