Synopsis
=======
curl is vulnerable to a buffer overflow which could lead to the
execution of arbitrary code.

Background
=========
curl is a command line tool for transferring files via many different
protocols.

Affected packages
================
    -------------------------------------------------------------------
     Package        /  Vulnerable  /                        Unaffected
    -------------------------------------------------------------------
  1  net-misc/curl      < 7.13.1                             >= 7.13.1

Description
==========
curl fails to properly check boundaries when handling NTLM
authentication.

Impact
=====
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.

Workaround
=========
Disable NTLM authentication by not using the --anyauth or --ntlm
options.

Resolution
=========
All curl users should upgrade to the latest version:

    # emerge --sync
    # emerge --ask --oneshot --verbose ">=net-misc/curl-7.13.1"
