TITLE

Netty  Resource exhaustion vulnerability in

DESCRIPTION

The Snappy frame decoder function doesn't restrict the chunk length which may lead to excessive memory usage. Beside this it also may buffer reserved skippable chunks until the whole chunk was received which may lead to excessive memory usage as well. This vulnerability can be triggered by supplying malicious input that decompresses to a very big size (via a network stream or a file) or by sending a huge skippable chunk. Netty Exists in a resource exhaustion vulnerability.Service operation interruption (DoS) It may be in a state. Description: Red Hat Process Automation Manager is an open source business process management suite that combines process management and decision service management and enables business and IT users to create, manage, validate, and deploy process applications and decision services. It is recommended to halt the server by stopping the JBoss Application Server process before installing this update; after installing the update, restart the server by starting the JBoss Application Server process. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-5316-1 security@debian.org https://www.debian.org/security/ Markus Koschany January 11, 2023 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : netty CVE ID : CVE-2021-37136 CVE-2021-37137 CVE-2021-43797 CVE-2022-41881 CVE-2022-41915 Debian Bug : 1027180 1014769 1001437 Several out-of-memory, stack overflow or HTTP request smuggling vulnerabilities have been discovered in Netty, a Java NIO client/server socket framework, which may allow attackers to cause a denial of service or bypass restrictions when used as a proxy.
