CVE-2022-41318 Information

Description

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.
