The remote host is affected by the vulnerability described in GLSA-200502-04 (Squid: Multiple vulnerabilities)
Squid contains several vulnerabilities:
Buffer overflow when handling WCCP recvfrom() (CAN-2005-0211).
Loose checking of HTTP headers (CAN-2005-0173 and CAN-2005-0174).
Incorrect handling of LDAP login names with spaces (CAN-2005-0175).
Impact :
An attacker could exploit:
the WCCP buffer overflow to cause Denial of Service.
the HTTP header parsing vulnerabilities to inject arbitrary response data, potentially leading to content spoofing, web cache poisoning and other cross-site scripting or HTTP response splitting attacks.
the LDAP issue to login with several variations of the same login name, leading to log poisoning.
Workaround :
There is no known workaround at this time.
