Debian Security Advisory DSA-1843-2                    security@xxxxxxxxxx

Package        : squid3
Vulnerability  : several
Problem type   : remote
Debian-specific: no
Debian bug     : 538989 539160
CVE ID         : CVE-2009-2622 CVE-2009-2621

It was discovered that squid3, a high-performance proxy caching server for
web clients, is prone to several denial of service attacks.  Due to incorrect
bounds checking and insufficient validation while processing response and
request data an attacker is able to crash the squid daemon via crafted
requests or responses.

This update to DSA-1843-1 includes updated upstream patches which add
checks for a corner-case in which an incomplete server reply could
also lead to denial of service conditions as well as more debugging
information.


The squid package in the oldstable distribution (etch) is not affected
by this problem.

For the stable distribution (lenny), this problem has been fixed in
version 3.0.STABLE8-3+lenny2.

For the testing distribution (squeeze), this problem will be fixed soon.

For the unstable distribution (sid), this problem has been fixed in
version 3.0.STABLE18-1.


We recommend that you upgrade your squid3 packages.

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

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