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

John Heasman of NGSSoftware has discovered a stack-based buffer overflow in the StarCalc parser and an input validation error when processing metacharacters in a link. Also OpenOffice.Org includes code from libwpd making it vulnerable to heap-based overflows when converting WordPerfect document tables (GLSA 200704-07).

Impact

A remote attacker could entice a user to open a specially crafted document, possibly leading to execution of arbitrary code with the rights 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-2.1.0-r1"

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

 # emerge --sync
 # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.2.0"
