Debian Security Advisory DSA 751-1                     security@debian.org
http://www.debian.org/security/                             Martin Schulze
July 11th, 2005                         http://www.debian.org/security/faq
- --------------------------------------------------------------------------

Package        : squid
Vulnerability  : IP spoofing
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-1519
Debian Bug     : 309504

The upstream developers have discovered a bug in the DNS lookup code
of Squid, the popular WWW proxy cache.  When the DNS client UDP port
(assigned by the operating system at startup) is unfiltered and the
network is not protected from IP spoofing, malicious users can spoof
DNS lookups which could result in users being redirected to arbitrary
web sites.

For the old stable distribution (woody) this problem has been fixed in
version 2.4.6-2woody9.

For the stable distribution (sarge) this problem has already been
fixed in version squid-2.5.9-9.

For the unstable distribution (sid) this problem has already been
fixed in version squid-2.5.9-9.

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.
