CVE-2021-33620 (GCVE-0-2021-33620)

Vulnerability from cvelistv5 – Published: 2021-05-28 00:00 – Updated: 2024-08-03 23:58

Summary

Squid before 4.15 and 5.x before 5.0.6 allows remote servers to cause a denial of service (affecting availability to all clients) via an HTTP response. The issue trigger is a header that can be expected to exist in HTTP traffic without any malicious intent by the server.

Severity

6.5 (Medium)
