<description>
|
|
<p>
|
|
Frank Lichtenheld has discovered that the "sort_offline()"
|
|
function in texindex insecurely creates temporary files with
|
|
predictable filenames.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A local attacker could create symbolic links in the temporary
|
|
files directory, pointing to a valid file somewhere on the filesystem.
|
|
When texindex is executed, this would result in the file being
|
|
overwritten with the rights of the user running the application.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All Texinfo users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=sys-apps/texinfo-4.8-r1"</code>
