Detail

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.

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:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/haproxy-2.0.10"
