OpenOffice.org: User-assisted execution of arbitrary code

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

Sean Larsson (iDefense Labs) reported an integer overflow in the function rtl_allocateMemory() in the file sal/rtl/source/alloc_global.c.

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 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-2.4.1"

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

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.4.1"
