TITLE

Red Hat Security Advisory 2021-5129-06

DESCRIPTION

Netty is an open-source, asynchronous event-driven network application framework for rapid development of maintainable high performance protocol servers & clients. In Netty (io.netty:netty-codec-http2) before version 4.1.61.Final there is a vulnerability that enables request smuggling. The content-length header is not correctly validated if the request only uses a single Http2HeaderFrame with the endStream set to to true. This could lead to request smuggling if the request is proxied to a remote peer and translated to HTTP/1.1. This is a followup of GHSA-wm47-8v5p-wjpj/CVE-2021-21295 which did miss to fix this one case. This was fixed as part of 4.1.61.Final. Bugs fixed (https://bugzilla.redhat.com/): 1944888 - CVE-2021-21409 netty: Request smuggling via content-length header 2004133 - CVE-2021-37136 netty-codec: Bzip2Decoder doesn't allow setting size restrictions for decompressed data 2004135 - CVE-2021-37137 netty-codec: SnappyFrameDecoder doesn't restrict chunk length and may buffer skippable chunks in an unnecessary way 2030932 - CVE-2021-44228 log4j-core: Remote code execution in Log4j 2.x when logs contain an attacker-controlled string value 5.
