USN-410-1: poppler vulnerability

Publication date

19 January 2007

Overview

poppler vulnerability


Details

The poppler PDF loader library did not limit the recursion depth of
the page model tree. By tricking a user into opening a specially
crafter PDF file, this could be exploited to trigger an infinite loop
and eventually crash an application that uses this library.

kpdf in Ubuntu 5.10, and KOffice in all Ubuntu releases contains a
copy of this code and thus is affected as well.
