Overview
Affected versions of this package are vulnerable to Server-generated Error Message Containing Sensitive Information via improper handling of HTTP authentication credentials in error responses of request_hdrs buffer. An attacker can obtain sensitive authentication information by triggering error conditions and analyzing the resulting responses. This is only exploitable if debug information in administrator mailto links is enabled in the configuration.
##Workaround
This vulnerability can be mitigated by disabling debug information in administrator mailto links by configuring squid.conf with email_err_data off.
