Package        : xpdf-i
Vulnerability  : integer overflow
Problem-Type   : local, remote
Debian-specific: no
CVE Id         : CAN-2002-1384

iDEFENSE discovered an integer overflow in the pdftops filter from the
xpdf and xpdf-i packages that can be exploited to gain the privileges
of the target user.  This can lead to gaining privileged access to the
'lp' user if thee pdftops program is part of the print filter.

For the current stable distribution (woody) xpdf-i is only a dummy
package and the problem was fixed in xpdf already.

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-i 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.
