Vulnerability from osv_openeuler – Published: 2022-11-11 11:05 – Updated: 2026-08-06 11:05 – Source website

Summary

haproxy security update

Details

HAProxy is a free, very fast and reliable solution offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for very high traffic web sites and powers quite a number of the world's most visited ones.

Security Fix(es):

A flaw was found in the way HAProxy processed HTTP responses containing the "Set-Cookie2" header. This flaw could allow an attacker to send crafted HTTP response packets which lead to an infinite loop, eventually resulting in a denial of service condition. The highest threat from this vulnerability is availability.(CVE-2022-0711)

Severity

7.5 (High)
