Description
===========

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).

Impact
======

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.

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-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"
