Description
An issue was discovered in Squid before 4.10. Due to incorrect input validation, the NTLM authentication credentials parser in ext_lm_group_acl may write to memory outside the credentials buffer.

This leads to the Squid process also terminating and a denial of service for all clients using the proxy.
