Debian Security Advisory DSA 667-1 security@debian.org

Package : squid
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.
