Classification: Other
Netty is an open-source, asynchronous event-driven network application
framework. The package `io.netty:netty-codec-http` prior to version
4.1.77.Final contains an insufficient fix for CVE-2021-21290. When Netty's
multipart decoders are used local information disclosure can occur via the
local system temporary directory if temporary storing uploads on the disk is
enabled. This only impacts applications running on Java version 6 and lower.
Additionally, this vulnerability impacts code running on Unix-like systems, and
very old versions of Mac OSX and Windows as they all share the system temporary
directory between all users. Version 4.1.77.Final contains a patch for this
vulnerability. As a workaround, specify one's own `java.io.tmpdir` when
starting the JVM or use DefaultHttpDataFactory.setBaseDir(...) to set the
directory to something that is only readable by the current user.
