Сводка

Multiple vulnerabilities have been reported in OpenOffice.org, possibly allowing for user-assisted execution of arbitrary code.

Назначение

OpenOffice.org is an open source office productivity suite, including word processing, spreadsheet, presentation, drawing, data charting, formula editing, and file conversion facilities.

Уязвимые пакеты

Пакет	Уязвимый	Нетронутый	Архитектура(ы)
app-office/openoffice	< 2.4.0	>= 2.4.0	All supported architectures
app-office/openoffice-bin	< 2.4.0	>= 2.4.0	All supported architectures

Описание

iDefense Labs reported multiple vulnerabilities in OpenOffice.org:

multiple heap-based buffer overflows when parsing the "Attribute" and "Font" Description records of Quattro Pro (QPRO) files (CVE-2007-5745),
an integer overflow when parsing the EMR_STRETCHBLT record of an EMF file, resulting in a heap-based buffer overflow (CVE-2007-5746),
an integer underflow when parsing Quattro Pro (QPRO) files, resulting in an excessive loop and a stack-based buffer overflow (CVE-2007-5747),
and a heap-based buffer overflow when parsing the "DocumentSummaryInformation" stream in an OLE file (CVE-2008-0320).

Furthermore, Will Drewry (Google Security) reported vulnerabilities in the memory management of the International Components for Unicode (CVE-2007-4770, CVE-2007-4771), which was resolved with GLSA 200803-20. However, the binary version of OpenOffice.org uses an internal copy of said library.

Воздействие

A remote attacker could entice a user to open a specially crafted document, possibly resulting in the remote execution of arbitrary code with the privileges of the user running OpenOffice.org.

Обход

There is no known workaround at this time.

Решение

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

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/openoffice-2.4.0"

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


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.4.0"
