CVE-2019-18676 (GCVE-0-2019-18676)

Vulnerability from cvelistv5

Published

2019-11-26 16:23

Modified

2024-08-05 01:54

Severity ?

CWE

Summary

An issue was discovered in Squid 3.x and 4.x through 4.8. Due to incorrect input validation, there is a heap-based buffer overflow that can result in Denial of Service to all clients using the proxy. Severity is high due to this vulnerability occurring before normal security checks; any remote client that can reach the proxy port can trivially perform the attack via a crafted URI scheme.
