Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

Clojure (org.clojure:clojure) versions 1.7.0 up to 1.11.2 (excluding 1.11.2 itself) and 1.12.0-alpha1 up to 1.12.0-alpha9 (excluding that version) are affected. An attacker who can supply serialized Java objects to a program that calls ObjectInputStream.readObject() on untrusted data can craft a serialized map with an infinite Clojure seq as a key, causing the reading thread to loop forever and denying service. Upgrade to Clojure 1.11.2 or 1.12.0-alpha9. Avoid deserializing untrusted data with ObjectInputStream, as that is inherently unsafe on the JVM.
