<p>
cURL is a command line tool and library for transferring files via
many different protocols. It supports NTLM authentication to retrieve
files from Windows-based systems.
</p>

<description>
<p>
iDEFENSE reported that insufficient bounds checking on a memcpy()
of the supplied NTLM username can result in a stack overflow.
</p>
</description>
<impact type="normal">
<p>
A remote attacker could setup a malicious server and entice an
user to connect to it using a cURL client, potentially leading to the
execution of arbitrary code with the permissions of the user running
cURL.
</p>
</impact>
<workaround>
<p>
Disable NTLM authentication by not using the --anyauth or --ntlm
options when using cURL (the command line version). Workarounds for
programs that use the cURL library depend on the configuration options
presented by those programs.
</p>
</workaround>
<resolution>
<p>
All cURL users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose &quot;&gt;=net-misc/curl-7.15.0&quot;</code>
</resolution>
