Memory exhaustion in http4s-async-http-client with large or malicious compressed responses

Impact

A server we connect to with http4s-async-http-client could theoretically respond with a large or malicious compressed stream and exhaust memory in the client JVM. It does not affect http4s servers, other client backends, or clients that speak only to trusted servers. This is related to a transitive dependency on netty-codec-4.1.45.Final, which is affected by CVE-2020-11612.

Patches

Upgrade to http4s-async-http-client >= 0.21.8. All 1.0 milestones are also safe.

Workarounds

Add an explicit runtime dependency on async-http-client's netty dependencies that evicts them to an unaffected version:

libraryDependencies ++= Seq( "io.netty" % "netty-codec" % "4.1.53.Final" % Runtime, "io.netty" % "netty-codec-socks" % "4.1.53.Final" % Runtime, "io.netty" % "netty-handler-proxy" % "4.1.53.Final" % Runtime, "io.netty" % "netty-common" % "4.1.53.Final" % Runtime, "io.netty" % "netty-transport" % "4.1.53.Final" % Runtime, "io.netty" % "netty-handler" % "4.1.53.Final" % Runtime, "io.netty" % "netty-resolver-dns" % "4.1.53.Final" % Runtime )
