Title: HAProxy: Arbitrary code execution (GLSA 202012-22)
Severity: normal
Exploitable: remote
Date: 2020-12-24
Bug(s): #715944
ID: 202012-22
Synopsis
A buffer overflow in HAProxy might allow an attacker to execute
arbitrary code.
Background
HAProxy is a TCP/HTTP reverse proxy for high availability environments.
Affected Packages
Package: net-proxy/haproxy
Vulnerable: < 2.1.4
Unaffected: >= 2.0.13
Unaffected: >= 2.1.4
Architectures: All supported architectures
Description
It was discovered that HAProxy incorrectly handled certain HTTP/2
headers.
Impact
A remote attacker, by sending a specially crafted HTTP/2 request, could
possibly execute arbitrary code with the privileges of the process, or
cause a Denial of Service condition.
Workaround
Disable HTTP/2 support.
Resolution
All HAProxy 2.0.x users should upgrade to the latest version: | Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/haproxy-2.0.13:0/2.0"
|
All other HAProxy users should upgrade to the latest version: | Code: | # emerge --sync
# emerge --ask --oneshot --verbose ">=net-proxy/haproxy-2.1.4"
