USN-410-2: teTeX vulnerability

Publication date

26 January 2007

Overview

teTeX vulnerability

Releases

Details

USN-410-1 fixed vulnerabilities in the poppler PDF loader library. This
update provides the corresponding updates for a copy of this code in
tetex-bin in Ubuntu 5.10. Versions of tetex-bin after Ubuntu 5.10 use
poppler directly and do not need a separate update.

Original advisory 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.
