OpenOffice.org: Two buffer overflows

OpenOffice.org: Two buffer overflows Multiple vulnerabilities have been discovered in OpenOffice.org, allowing for the remote execution of arbitrary code. openoffice July 02, 2007 July 02, 2007: 01 181773 remote 2.2.1 2.2.1 2.2.1 2.2.1

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

John Heasman of NGSSoftware has discovered a heap-based buffer overflow when parsing the "prdata" tag in RTF files where the first token is smaller than the second one (CVE-2007-0245). Additionally, the OpenOffice binary program is shipped with a version of FreeType that contains an integer signedness error in the n_points variable in file truetype/ttgload.c, which was covered by GLSA 200705-22 (CVE-2007-2754).

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

There is no known workaround at this time.

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


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/openoffice-2.2.1"

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


    # emerge --sync
    # emerge --ask --oneshot --verbose ">=app-office/openoffice-bin-2.2.1"
