xpdf crashes with SIGSEGV (Segmentation fault) when opening PDF document

[Michael Mess]

xpdf crashes with SIGSEGV when opening the PDF file attached to this ticket.

As PDF files are often downloaded from the internet and this bug could be possibly exploited by a malicious document for executing questionable code as the user executing xpdf, I have marked it as security issue.
This needs to be reviewed.
