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. -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 ==================================================================== Red Hat Security Advisory Synopsis: Moderate: OpenShift Container Platform 4.7.41 security update Advisory ID: RHSA-2022:0114-01 Product: Red Hat OpenShift Enterprise Advisory URL: https://access.redhat.com/errata/RHSA-2022:0114 Issue date: 2022-01-19 CVE Names: CVE-2021-39241 CVE-2021-40346 ==================================================================== 1.
