<background>
<p>
curl is a command line tool for transferring files via many
different protocols.
</p>
</background>
<description>
<p>
curl fails to properly check boundaries when handling NTLM
authentication.
</p>
</description>
<impact type="normal">
<p>
With a malicious server an attacker could send a carefully crafted
NTLM response to a connecting client 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.
</p>
</workaround>
<resolution>
<p>
All curl users should upgrade to the latest version:
</p>
<code>
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-misc/curl-7.13.1"</code>
</resolution>
