<p>
Tavis Ormandy from Gentoo Linux discovered that mtink uses insecure
permissions on temporary files.
</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
mtink is executed, this would result in the file being overwritten with
the rights of the user running the utility, which could be the root
user.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All mtink users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-print/mtink-1.0.5&quot;</code>
</resolution>
