CVE-2022-41881: High severity IBM Disconnected Log Collector vulnerability

Published Dec 12, 2022
·
Updated

A flaw was found in codec-haproxy from the Netty project. This flaw allows an attacker to build a malformed crafted message and cause infinite recursion, causing stack exhaustion and leading to a denial of service (DoS).

Other sources

Netty is vulnerable to a denial of service, caused by a StackOverflowError in HAProxyMessageDecoder. By sending a specially-crafted message, a remote attacker could exploit this vulnerability to cause an infinite recursion, and results in a denial of service condition.

Netty project is an event-driven asynchronous network application framework. In versions prior to 4.1.86.Final, a StackOverflowError can be raised when parsing a malformed crafted message due to an infinite recursion. This issue is patched in version 4.1.86.Final. There is no workaround, except using a custom HaProxyMessageDecoder.
