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

Two heap-based buffer overflows when processing WMF files (CVE-2008-2237) and EMF files (CVE-2008-2238) were discovered. Dmitry E. Oboukhov also reported an insecure temporary file usage within the senddoc script (CVE-2008-4937).

Impact

A remote attacker could entice a user to open a specially crafted document, resulting in the remote execution of arbitrary code. A local attacker could perform symlink attacks to overwrite arbitrary files on the system. Both cases happen with the privileges of the user running the application.

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-3.0.0"

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

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-3.0.0"
