The remote host is affected by the vulnerability described in GLSA-200501-25 (Squid: Multiple vulnerabilities)
Squid contains a vulnerability in the gopherToHTML function (CAN-2005-0094) and incorrectly checks the 'number of caches' field when parsing WCCP_I_SEE_YOU messages (CAN-2005-0095). Furthermore the NTLM code contains two errors. One is a memory leak in the fakeauth_auth helper (CAN-2005-0096) and the other is a NULL pointer dereferencing error (CAN-2005-0097). Finally Squid also contains an error in the ACL parsing code (CAN-2005-0194).
Impact :
With the WCCP issue an attacker could cause denial of service by sending a specially crafted UDP packet. With the Gopher issue an attacker might be able to execute arbitrary code by enticing a user to connect to a malicious Gopher server. The NTLM issues could lead to denial of service by memory consumption or by crashing Squid. The ACL issue could lead to ACL bypass.
Workaround :
There is no known workaround at this time.
