<description>
|
|
<p>
|
|
Javier Fernandez-Sanguino has discovered that the lib/toascii.nw
|
|
and shell/roff.mm scripts insecurely create temporary files with
|
|
predictable filenames.
|
|
</p>
|
|
</description>
|
|
<impact type="normal">
|
|
<p>
|
|
A local attacker could create symbolic links in the temporary file
|
|
directory, pointing to a valid file somewhere on the filesystem. When
|
|
an affected script is called, this would result in the file being
|
|
overwritten with the rights of the user running the script.
|
|
</p>
|
|
</impact>
|
|
<workaround>
|
|
<p>
|
|
There is no known workaround at this time.
|
|
</p>
|
|
</workaround>
|
|
<resolution>
|
|
<p>
|
|
All noweb users should upgrade to the latest version:
|
|
</p>
|
|
<code>
|
|
# emerge --sync
|
|
# emerge --ask --oneshot --verbose ">=app-text/noweb-2.9-r5"</code>
