(RHSA-2007:0069) Important: openoffice.org security update

OpenOffice.org is an office productivity suite that includes desktop
applications such as a word processor, spreadsheet, presentation manager,
formula editor, and drawing program.

John Heasman discovered a stack overflow in the StarCalc parser in
OpenOffice. An attacker could create a carefully crafted StarCalc file
that could cause OpenOffice.org to crash or possibly execute arbitrary code
if the file was opened by a victim. (CVE-2007-0238)

Flaws were discovered in the way OpenOffice.org handled hyperlinks. An
attacker could create an OpenOffice.org document which could run commands
if a victim opened the file and clicked on a malicious hyperlink.
(CVE-2007-0239)

All users of OpenOffice.org are advised to upgrade to these updated
packages, which contain a backported fix to correct this issue.
