Red Hat Bugzilla – Bug 474455
CVE-2008-5298 chm2pdf insecure temporary file use
Last modified: 2016-03-04 06:32:13 EST
chm2pdf 0.9 uses temporary files in directories with fixed names, which allows local users to cause a denial of service (chm2pdf failure) of other users by creating those directories ahead of time.

This flaw was corrected in Fedora 14:
and Fedora 13:
