High

AV:N/AC:L/Au:N/C:N/I:N/A:C

Name of the Vulnerable Software and Affected Versions Netty versions 4.1.124.Final and below Netty versions 4.2.4.Final and below

Description Netty is an asynchronous event-driven network application framework. Certain decompression decoders, including BrotliDecoder, can allocate a large number of byte buffers when provided with specially crafted input, potentially leading to a denial of service. The decompress function within BrotliDecoder repeatedly calls pull, decompressing data in 64KB chunks, and the resulting buffers remain reachable until an out-of-memory (OOM) error occurs.

Recommendations Update to Netty version 4.1.125.Final or later. Update to Netty version 4.2.5.Final or later.
