Red Hat: An updated gpdf package fixes a security issue
 by Patrick Lenz, in Security - Sun, May 11th 2008 11:46 UTC

gpdf is a GNOME-based viewer for Portable Document Format (PDF) files. Kees Cook discovered a flaw in the way gpdf displayed malformed fonts embedded in PDF files. An attacker could create a malicious PDF file that would cause gpdf to crash, or, potentially, execute arbitrary code when opened. Fixed packages are available from updates.redhat.com.
