Date:	04/01/2020
Bugs:	#701842
ID:	202004-01

Synopsis

A vulnerability in HAProxy might lead to remote execution of arbitrary code.

Background

HAProxy is a TCP/HTTP reverse proxy for high availability environments.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
net-proxy/haproxy	< 2.0.10	>= 1.8.23	All supported architectures

Description

It was discovered that HAProxy incorrectly handled certain HTTP/2 headers.

Impact

A remote attacker could send a specially crafted HTTP/2 header, possibly resulting in execution of arbitrary code with the privileges of the process or a Denial of Service condition.

Workaround

There is no known workaround at this time.

Resolution

All HAProxy 1.8.x users should upgrade to the latest version:

      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-proxy/haproxy-1.8.23"

All HAProxy 1.9.x users should upgrade to the latest version:


      # emerge --sync
      # emerge --ask --oneshot --verbose ">=net-proxy/haproxy-1.9.13"

All HAProxy 2.0.x users should upgrade to the latest version:
