Ulf Harnhammar reported a possible buffer overflow in the handling
of TFTP URLs in libcurl due to the lack of boundary checks.
</p>
</description>
<impact type="normal">
<p>
An attacker could exploit this vulnerability to compromise a
user's system by enticing the user to request a malicious URL with
cURL/libcurl or to use a HTTP server redirecting to a malicious TFTP
URL.
</p>
</impact>
<workaround>
<p>
There is no known workaround at this time.
</p>
</workaround>
<resolution>
<p>
All cURL users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose "&gt;=net-misc/curl-7.15.1-r1"</code>
</resolution>
