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.

Summary


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.
