o3read is a standalone converter for OpenOffice.org files. It
|
|
allows a user to dump the contents tree (o3read) and convert to plain
|
|
text (o3totxt) or to HTML (o3tohtml) Writer and Calc files.

|
|
Wiktor Kopec discovered that the parse_html function in o3read.c
|
|
copies any number of bytes into a 1024-byte t[] array.

<impact type="normal">
|
|
<p>
|
|
Using a specially crafted file, possibly delivered by e-mail or
|
|
over the Web, an attacker may execute arbitrary code with the
|
|
permissions of the user running o3read.
|

</p>

|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.

</workaround>
|

<resolution>
|
|
<p>
|
|
All o3read users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/o3read-0.0.4"</code>
