USN-410-1: poppler vulnerability

19 January 2007

poppler vulnerability



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.

Update instructions

The problem can be corrected by updating your system to the following package versions:

Ubuntu 6.10
  • libpoppler1 - 0.5.4-0ubuntu4.1
  • kword - 1:1.5.2-0ubuntu2.1
Ubuntu 6.06
  • libpoppler1 - 0.5.1-0ubuntu7.1
  • kword - 1:1.5.0-0ubuntu9.1
Ubuntu 5.10
  • kpdf - 4:3.4.3-0ubuntu2.6
  • kword - 1:1.4.1-0ubuntu7.5
  • libpoppler0c2 - 0.4.2-0ubuntu6.8

In general, a standard system upgrade is sufficient to effect the
necessary changes.
