Debian Security Advisory DSA-1482-1                  security@debian.org
http://www.debian.org/security/                       Moritz Muehlenhoff

- ------------------------------------------------------------------------

Package        : squid
Vulnerability  : programming error
Problem type   : remote
Debian-specific: no
CVE Id(s)      : CVE-2007-6239

It was discovered that malformed cache update replies against the Squid
WWW proxy cache could lead to the exhaustion of system memory, resulting
in potential denial of service.

For the stable distribution (etch), this problem has been fixed in
version 2.6.5-6etch1.

For the old stable distribution (sarge), the update cannot currently
be processed on the buildd security network due to a bug in the archive
management script. This will be resolved soon. An update for i386
is temporarily available at at http://people.debian.org/~jmm/squid/.

We recommend that you upgrade your squid 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
        will install corrected packages

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


Debian 4.0 (stable)
- -------------------

Stable updates are available for alpha, amd64, arm, hppa, i386, ia64, mips, mipsel, powerpc, s390 and sparc.
