NVD Description

Note: Versions mentioned in the description apply only to the upstream eap7-activemq-artemis package and not the eap7-activemq-artemis package as distributed by RHEL. See How to fix? for RHEL:8 relevant fixed versions and status.

Netty is an asynchronous, event-driven network application framework. Prior to 4.2.13.Final and 4.1.133.Final, Netty's DNS codec does not enforce RFC 1035 domain name constraints during either encoding or decoding. This creates a bidirectional attack surface: malicious DNS responses can exploit the decoder, and user-influenced hostnames can exploit the encoder. This vulnerability is fixed in 4.2.13.Final and 4.1.133.Final.
