http://security.gentoo.org/

Severity:	normal
Title:	OpenOffice.Org: DOC document Heap Overflow
Date:	04/15/2005
Bugs:	#88863
ID:	200504-13

Synopsis

OpenOffice.Org is vulnerable to a heap overflow when processing DOC documents, which could lead to arbitrary code execution.

Background

OpenOffice.org is an office productivity suite, including word processing, spreadsheets, presentations, drawings, data charting, formula editing, and file conversion facilities.

Affected packages

Package	Vulnerable	Unaffected	Architecture(s)
app-office/openoffice	< 1.1.4-r1	>= 1.1.4-r1	All supported architectures
app-office/openoffice-bin	< 1.1.4-r1	>= 1.1.4-r1	All supported architectures
app-office/openoffice-ximian	< 1.3.9-r1	>= 1.3.9-r1	All supported architectures

Description

AD-LAB has discovered a heap overflow in the "StgCompObjStream::Load()" function when processing DOC documents.

Impact

An attacker could design a malicious DOC document containing a specially crafted header which, when processed by OpenOffice.Org, would result in the execution of arbitrary code with the rights 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-1.1.4-r1"

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


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-1.1.4-r1"

All OpenOffice.Org Ximian users should upgrade to the latest version:


    # emerge --sync
    # emerge --ask --oneshot --verbose app-office/openoffice-ximian

Note to PPC users: There is no stable OpenOffice.Org fixed version for the PPC architecture. Affected users should switch to the latest OpenOffice.Org Ximian version.

Note to SPARC users: There is no stable OpenOffice.Org fixed version for the SPARC architecture. Affected users should switch to the latest OpenOffice.Org Ximian version.
