Squid < 2.5.STABLE7 NTLM Authentication DoS



The remote proxy server is vulnerable to a Denial of Service (DoS) attack.


The remote server is running a Squid proxy server. This version is reported vulnerable to a remote denial of service in the NTLM authentication routine. If NTLM authentication is enabled, an attacker may deny service to legitimate users by sending malformed NTLMSSP packets.


Upgrade to Squid version 2.5.STABLE7 or later, or apply the vendor-supplied patch.
