Descriptions

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.

Netty es un framework de aplicaciones de red asíncronas de código abierto. El paquete "io.netty:netty-codec-http" versiones anteriores a 4.1.77.Final contiene una corrección insuficiente para CVE-2021-21290. Cuando son usados los descodificadores multiparte de Netty, puede producirse una divulgación de información local por medio del directorio temporal del sistema local si es habilitado el almacenamiento temporal de cargas en el disco. Esto sólo afecta a las aplicaciones que son ejecutadas en la versión 6 de Java e inferior. Además, esta vulnerabilidad afecta al código que es ejecutado en sistemas tipo Unix, y a versiones muy antiguas de Mac OSX y Windows, ya que todos ellos comparten el directorio temporal del sistema entre todos los usuarios. La versión 4.1.77.Final contiene un parche para esta vulnerabilidad. Como mitigación, especifique su propio "java.io.tmpdir" cuando inicie la JVM o use DefaultHttpDataFactory.setBaseDir(...) para establecer el directorio en algo que sólo pueda leer el usuario actual

CVE-2021-21290 contains an incomplete fix, and this addresses the issue found in netty. When using multipart decoders in netty, local information disclosure can occur via the local system temporary directory if temporary storing of uploads on the disk is enabled.
