TITLE

HAProxy Input Validation Error Vulnerability

DESCRIPTION

An integer overflow exists in HAProxy 2.0 through 2.5 in htx_add_header that can be exploited to perform an HTTP request smuggling attack, allowing an attacker to bypass all configured http-request HAProxy ACLs and possibly other ACLs. HAProxy is an open source TCP/HTTP load balancing server from the French HAProxy= company. = There is an input validation error vulnerability in HAProxy, which stems from the lack of header name length checking in the htx_add_header() and htx_add_trailer() functions in HAProxy, which can be exploited by attackers to cause request smuggling attacks or response splitting attacks. Description: Red Hat Advanced Cluster Management for Kubernetes 2.2.11 images Red Hat Advanced Cluster Management for Kubernetes provides the capabilities to address common challenges that administrators and site reliability engineers face as they work across a range of public and private cloud environments. Clusters and applications are all visible and managed from a single console — with security policy built in.
