Synopsis

Several format string vulnerabilities are present in the Neon library
included in OpenOffice.org, allowing remote execution of arbitrary
code when connected to an untrusted WebDAV server.

Background

OpenOffice.org is an office productivity suite, including word
processing, spreadsheets, presentations, drawings, data charting,
formula editing, and file conversion facilities.

Description

OpenOffice.org includes code from the Neon library in functions related
to publication on WebDAV servers. This library is vulnerable to several
format string attacks.

Impact

If you use the WebDAV publication and connect to a malicious WebDAV
server, this server can exploit these vulnerabilities to execute
arbitrary code with the rights of the user running OpenOffice.org.

Workaround

As a workaround, you should not use the WebDAV publication facilities.

Resolution

There is no binary version including the fix yet. All users of the
openoffice-bin and ximian-openoffice-bin packages making use of the
WebDAV publication functions should upgrade to the latest version of
the corresponding source-based package.

openoffice users on the x86 architecture should:

# emerge sync

# emerge -pv &quot;&gt;=app-office/openoffice-1.1.1-r1&quot;
# emerge &quot;&gt;=app-office/openoffice-1.1.1-r1&quot;

openoffice users on the sparc architecture should:

# emerge sync

# emerge -pv &quot;&gt;=app-office/openoffice-1.1.0-r3&quot;
# emerge &quot;&gt;=app-office/openoffice-1.1.0-r3&quot;

openoffice users on the ppc architecture should:

# emerge sync

# emerge -pv &quot;&gt;=app-office/openoffice-1.0.3-r1&quot;
# emerge &quot;&gt;=app-office/openoffice-1.0.3-r1&quot;

openoffice-ximian users should:

# emerge sync

# emerge -pv &quot;&gt;=app-office/openoffice-ximian-1.1.51-r1&quot;
# emerge &quot;&gt;=app-office/openoffice-ximian-1.1.51-r1&quot;
