OpenOffice.org: Multiple vulnerabilities

Background

OpenOffice.org is an open source office productivity suite, including word processing, spreadsheet, presentation, drawing, data charting, formula editing, and file conversion facilities.

Description

iDefense Labs reported multiple vulnerabilities in OpenOffice.org:

• multiple heap-based buffer overflows when parsing the “Attribute” and “Font” Description records of Quattro Pro (QPRO) files (CVE-2007-5745),
• an integer overflow when parsing the EMR_STRETCHBLT record of an EMF file, resulting in a heap-based buffer overflow (CVE-2007-5746),
• an integer underflow when parsing Quattro Pro (QPRO) files, resulting in an excessive loop and a stack-based buffer overflow (CVE-2007-5747),
• and a heap-based buffer overflow when parsing the “DocumentSummaryInformation” stream in an OLE file (CVE-2008-0320).

Furthermore, Will Drewry (Google Security) reported vulnerabilities in the memory management of the International Components for Unicode (CVE-2007-4770, CVE-2007-4771), which was resolved with GLSA 200803-20. However, the binary version of OpenOffice.org uses an internal copy of said library.

Impact

A remote attacker could entice a user to open a specially crafted document, possibly resulting in the remote execution of arbitrary code with the privileges of the user running OpenOffice.org.

Workaround

There is no known workaround at this time.

Resolution

All OpenOffice.org users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-office/openoffice-2.4.0"

All OpenOffice.org binary users should upgrade to the latest version:

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.4.0"
