TITLE

HAProxy  Integer overflow vulnerability in

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 Exists in an integer overflow vulnerability.Information may be tampered with. 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: SHA512 - ------------------------------------------------------------------------- Debian Security Advisory DSA-4968-1 security@debian.org https://www.debian.org/security/ Salvatore Bonaccorso September 07, 2021 https://www.debian.org/security/faq - ------------------------------------------------------------------------- Package : haproxy CVE ID : CVE-2021-40346 Ori Hollander reported that missing header name length checks in the htx_add_header() and htx_add_trailer() functions in HAProxy, a fast and reliable load balancing reverse proxy, could result in request smuggling attacks or response splitting attacks. Additionally this update addresses #993303 introduced in DSA 4960-1 causing HAProxy to fail serving URLs with HTTP/2 containing '//'. For the stable distribution (bullseye), this problem has been fixed in version 2.2.9-2+deb11u2. We recommend that you upgrade your haproxy packages.
