Package        : xpdf-1.01-5		
Vulnerability  : integer overflow
Problem-Type   : local and remote
PLD-specific   : no
CVE references : CAN-2002-1384

The pdftops filter in the Xpdf and CUPS packages contains an integer
overflow that can be exploited to gain the privileges of the target user
or in some cases the increased privileges of the 'lp' user if installed
setuid. There are multiple ways of exploiting this vulnerability.

The above problems have been fixed in version 1.01-6 for the
current stable distribution (ra).

We recommend that you upgrade your xpdf packages.

wget -c url
	will fetch the file for you
rpm -Uhv file(s)*.rpm
        will upgrade the referenced file.

If you are using "poldek" - the package manager, use the line as given below
for upgrade packages

poldek --update
        will update the internal database
poldek --upgrade 'xpdf*'
        will install corrected packages

If you are using "apt" - the package manager, use the line as given below
for upgrade packages

apt-get update
        will update the internal database
apt-get upgrade 'xpdf*'
        will install corrected packages
