Synopsis ========
A truncation error and integer overflows in the EMF/WMF file handling of OpenOffice.org could be exploited to execute 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 ------------------------------------------------------------------- 1 app-office/openoffice-bin < 2.1.0 >= 2.1.0 2 app-office/openoffice < 2.0.4 >= 2.0.4 ------------------------------------------------------------------- 2 affected packages on all of their supported architectures. -------------------------------------------------------------------
Description ===========
John Heasman of NGSSoftware has discovered integer overflows in the EMR_POLYPOLYGON and EMR_POLYPOLYGON16 processing and an error within the handling of META_ESCAPE records.
Impact ======
An attacker could exploit these vulnerabilities to cause heap overflows and potentially execute arbitrary code with the privileges of the user running OpenOffice.org by enticing the user to open a document containing a malicious WMF/EMF file.
Workaround ==========
There is no known workaround known at this time.
Resolution ==========
All OpenOffice.org binary users should update to version 2.1.0 or later:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.1.0"
All OpenOffice.org users should update to version 2.0.4 or later:
# emerge --sync # emerge --ask --oneshot --verbose ">=app-office/openoffice-2.0.4"
