Machine-written summary

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

The netty-incubator-codec-bhttp package, versions before 0.0.23.Final, does not enforce limits on the encoded variable lengths used for fields in its binary HTTP parser. A remote peer controls these lengths and can cause the parser to buffer data indefinitely, which can lead to an out-of-memory condition. Upgrade to 0.0.23.Final or later.
