CVE-2022-41318 (GCVE-0-2022-41318)

Vulnerability from cvelistv5 – Published: 2022-12-25 00:00 – Updated: 2025-04-14 18:33

Summary

A buffer over-read was discovered in libntlmauth in Squid 2.5 through 5.6. Due to incorrect integer-overflow protection, the SSPI and SMB authentication helpers are vulnerable to reading unintended memory locations. In some configurations, cleartext credentials from these locations are sent to a client. This is fixed in 5.7.

Severity

8.6 (High)
