Machine-written summary

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

The protobuf-java, protobuf-javalite, protobuf-kotlin and protobuf-kotlin-lite Maven packages, and the google-protobuf RubyGems package, are affected in versions before 3.25.5, from 4.0.0-RC1 up to 4.27.5, and from 4.28.0-RC1 up to 4.28.2. An attacker who can supply a maliciously crafted message to a parser can trigger unbounded recursion while parsing nested groups as unknown fields or map fields, causing a StackOverflow error and crashing the program. Upgrade to 3.25.5, 4.27.5, or 4.28.2, depending on your release line.
