The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available. - Netty is an asynchronous, event-driven network application framework. Prior to versions 4.1.136.Final and 4.2.16.Final, the Bzip2Decoder handler in Netty's...

CVE-2026-59901

A flaw was found in the netty-codec-compression component of Netty. This vulnerability, caused by a logic error in the bzip2 decoder, allows a remote attacker to send specially crafted bzip2-compressed data. Processing this malformed data can trigger an infinite loop, causing the decoder thread t...
