Debian-specific: no
CVE Id         : CAN-2002-1384

iDEFENSE discovered an integer overflow in the pdftops filter from the

user if thee pdftops program is part of the print filter.

For the current stable distribution (woody) this problem has been
fixed in version 1.00-3.1.

For the old stable distribution (potato) this problem has been
fixed in version 0.90-8.1.

For the unstable distribution (sid) this problem has been
fixed in version 2.01-2.

We recommend that you upgrade your xpdf package.

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.
