HIGHSquid 2.5-5.6 - Buffer Over-read in libntlmauth via Integer Overflow
Title source: llmDescription
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.
