There is a security problem when using tmpnam() and fopen() in
versions prior to 0.91. The problem is seen when a root user
overwrites files where a symlink is created between the calls to
tmpname() and fopen().
There is also a problem with URL-type links in PDF documents
that contain quote characters which could also be used to execute
The xpdf-0.91 fixes both these security problems.
