[GLSA-200502-04] Squid: Multiple vulnerabilities

Vulnerability Assessment Summary
Squid: Multiple vulnerabilities

Detailed Explanation for this Vulnerability Assessment
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()
(CVE-2005-0211).
Loose checking of HTTP headers (CVE-2005-0173 and
CVE-2005-0174).
Incorrect handling of LDAP login names with spaces
(CVE-2005-0175).

Impact

A possible hacker 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.
