Severity:	normal
Title:	OpenOffice.org: Heap-based buffer overflow
Date:	10/23/2007
Bugs:	#192818
ID:	200710-24

Synopsis

A heap-based buffer overflow vulnerability has been discovered in OpenOffice.org, allowing for the remote 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.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-office/openoffice	< 2.3.0	>= 2.3.0	All supported architectures
app-office/openoffice-bin	< 2.3.0	>= 2.3.0	All supported architectures

Description

iDefense Labs reported that the TIFF parsing code uses untrusted values to calculate buffer sizes, which can lead to an integer overflow resulting in heap-based buffer overflow.

Impact

A remote attacker could entice a user to open a specially crafted document, possibly leading to 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-2.3.0"

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


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.3.0"
