RHSA-2007:0033 - Security Advisory

Topic

Updated openoffice.org packages to correct security issues are now
available for Red Hat Enterprise Linux 3 and 4.

This update has been rated as having important security impact by the Red
Hat Security Response Team.

Description

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

iDefense reported an integer overflow flaw in libwpd, a library used
internally to OpenOffice.org for handling Word Perfect documents. An
attacker could create a carefully crafted Word Perfect file that could
cause OpenOffice.org to crash or possibly execute arbitrary code if the
file was opened by a victim. (CVE-2007-1466)

John Heasman discovered a stack overflow in the StarCalc parser in
OpenOffice.org. 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 backported fixes for these issues.

Red Hat would like to thank Fridrich Štrba for alerting us to the issue
CVE-2007-1466 and providing a patch, and John Heasman for
CVE-2007-0238.
