Descriptions

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.

El proyecto Netty es un framework de aplicación de red asíncrona impulsado por eventos. En versiones anteriores a la 4.1.86.Final, se puede generar un StackOverflowError al analizar un mensaje manipulado con formato incorrecto debido a una recursividad infinita. Este problema se solucionó en la versión 4.1.86.Final. No existe ningún workaround, excepto utilizar un HaProxyMessageDecoder personalizado.

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).

Red Hat Single Sign-On is an integrated sign-on solution, available as a Red Hat JBoss Middleware for OpenShift containerized image. The Red Hat Single Sign-On for OpenShift image provides an authentication server that you can use to log in centrally, log out, and register. You can also manage user accounts for web applications, mobile applications, and RESTful web services. This erratum releases a new image for Red Hat Single Sign-On 7.6.3 for use within the Red Hat OpenShift Container Platform cloud computing Platform-as-a-Service for on-premise or private cloud deployments, aligning with the standalone product release. Issues addressed include denial of service and information leakage vulnerabilities.
