Bug Description
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.
