Package        : junkbuster
Vulnerability  : several
Problem-Type   : remote
Debian-specific: no
CVE ID         : CAN-2005-1108 CAN-2005-1109

Several bugs have been found in junkbuster, a HTTP proxy and filter.
The Common Vulnerability and Exposures project identifies the
following vulnerabilities:


    James Ranson discovered that an attacker can modify the referrer
    setting with a carefully crafted URL by accidently overwriting a
    global variable.


    Tavis Ormandy from the Gentoo Security Team discovered several
    heap corruptions due to inconsistent use of an internal function
    that can crash the daemon or possibly lead to the execution of
    arbitrary code.

For the stable distribution (woody) these problems have been fixed in
version 2.0.2-0.2woody1.

The unstable distribution (sid) doesn't contain the junkbuster package

We recommend that you upgrade your junkbuster 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.
