medium Tenable Cloud Security Plugin ID 462470

Description

There are packages installed that are affected by a vulnerability referenced in the following CVE:

 - Netty is an asynchronous event-driven network application framework for rapid development of maintainable
 high performance protocol servers & clients. In netty-codec-compression versions 4.1.124.Final and below,
 and netty-codec versions 4.2.4.Final and below, when supplied with specially crafted input, BrotliDecoder
 and certain other decompression decoders will allocate a large number of reachable byte buffers, which can
 lead to denial of service. BrotliDecoder.decompress has no limit in how often it calls pull, decompressing
 data 64K bytes at a time. The buffers are saved in the output list, and remain reachable until OOM is hit.
 This is fixed in versions 4.1.125.Final of netty-codec and 4.2.5.Final of netty-codec-compression.
 (CVE-2025-58057)

Solution

Update the io.netty:netty-codec library and its related packages to version 4.1.125.Final or later.
