NVD Description

Note: Versions mentioned in the description apply only to the upstream katello-client-bootstrap package and not the katello-client-bootstrap package as distributed by RHEL. See How to fix? for RHEL:7 relevant fixed versions and status.

The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder.
