Date: July 02, 2007
Bug(s): #181773
ID: 200707-02

Synopsis


Multiple vulnerabilities have been discovered in OpenOffice.org, allowing
for the remote execution of 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: app-office/openoffice
Vulnerable: < 2.2.1

Architectures: All supported architectures

Package: app-office/openoffice-bin
Vulnerable: < 2.2.1
Unaffected: >= 2.2.1

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:
