CVE-2020-11612 – netty: compression/decompression codecs don't enforce limits on buffer allocation sizes

https://notcve.org/view.php?id=CVE-2020-11612

The ZlibDecoders in Netty 4.1.x before 4.1.46 allow for unbounded memory allocation while decoding a ZlibEncoded byte stream. An attacker could send a large ZlibEncoded byte stream to the Netty server, forcing the server to allocate all of its free memory to a single decoder. El ZlibDecoders en Netty versiones 4.1.x anteriores a 4.1.46, permite una asignación de memoria ilimitada mientras decodifican un flujo de bytes de ZlibEncoded. Un atacante podría enviar una secuencia de bytes de ZlibEncoded grande hacia el servidor de Netty, forzando al servidor a asignar toda su memoria liberada a un único decodificador. A flaw was found in Netty in the way it handles the amount of data it compresses and decompresses. • https://github.com/netty/netty/compare/netty-4.1.45.Final...netty-4.1.46.Final https://github.com/netty/netty/issues/6168 https://github.com/netty/netty/pull/9924 https://lists.apache.org/thread.html/r14446ed58208cb6d97b6faa6ebf145f1cf2c70c0886c0c133f4d3b6f%40%3Ccommits.druid.apache.org%3E https://lists.apache.org/thread.html/r255ed239e65d0596812362adc474bee96caf7ba042c7ad2f3c62cec7%40%3Cissues.zookeeper.apache.org%3E https://lists.apache.org/thread.html/r281882fdf9ea89aac02fd2f92786693a956aac2ce9840cce87c7df6b%40%3Ccommits.zookeeper.apache. • CWE-400: Uncontrolled Resource Consumption CWE-770: Allocation of Resources Without Limits or Throttling •
