xpdf -- disk fill DoS vulnerability

xpdf is vulnerable to a denial of service vulnerability
which can cause xpdf to create an infinitely large file,
thereby filling up the /tmp partition, when opening a
specially crafted PDF file.
Note that several applications contains an embedded version
of xpdf, therefor making them the vulnerable to the same
DoS. In CUPS this vulnerability would cause the pdftops
filter to crash.
