[原文]Squid 2.5, when processing the configuration file, parses empty Access Control Lists (ACLs), including proxy_auth ACLs without defined auth schemes, in a way that effectively removes arguments, which could allow remote attackers to bypass intended ACLs if the administrator ignores the parser warnings.


[CNNVD]Squid 权限管理和访问控制漏洞(CNNVD-200505-311)

        Squid 2.5在处理配置文件时,采用一种有效删除参数的方式对空的访问控制列表(ACL)进行解析,其中包括不包含已定义验证方案的proxy_auth ACL,从而在如果管理员忽略解析器警告的情况下允许远程攻击者绕过设置的ACL。

Debian Security Advisory 667-1 - Several vulnerabilities have been discovered in Squid, the internet object cache, the popular WWW proxy cache.

Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE IDs        : CAN-2005-0173 CAN-2005-0175 CAN-2005-0194 CAN-2005-0211

Several vulnerabilities have been discovered in Squid, the internet
object cache, the popular WWW proxy cache.  The Common Vulnerabilities
and Exposures project identifies the following vulnerabilities:

CAN-2005-0173

    LDAP is very forgiving about spaces in search filters and this
    could be abused to log in using several variants of the login
    name, possibly bypassing explicit access controls or confusing
    accounting.

CAN-2005-0175

    Cache pollution/poisening via HTTP response splitting has been
    discovered.

CAN-2005-0194

    The meaning of the access controls becomes somewhat confusing if
    any of the referenced ACLs (access control lists) is declared
    empty, without any members.

CAN-2005-0211

    The length argument of the WCCP recvfrom() call is larger than it
    should be.  An attacker may send a larger than normal WCCP packet
    that could overflow a buffer.

For the stable distribution (woody) these problems have been fixed in
version 2.4.6-2woody6.

For the unstable distribution (sid) these problems have been fixed in
version 2.5.7-7.

We recommend that you upgrade your squid package.


Upgrade Instructions
- --------------------

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.
