Synopsis

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

2. Impact Information

Background

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

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.

3. Resolution Information

Workaround

There is no known workaround at this time.

Resolution

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

Code Listing 3.1: Resolution

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

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

Code Listing 3.2: Resolution

# 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:

Code Listing 3.3: Resolution

# 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.
