     Date: June 06, 2014
     Bugs: #349569
       ID: 201406-07

Synopsis
========

A buffer overflow in Echoping might allow remote attackers to cause a
Denial of Service condition.

Background
==========

Echoping is a small program to test performances of a
remote host by sending it TCP packets.

Affected packages
=================

    -------------------------------------------------------------------
     Package              /     Vulnerable     /            Unaffected
    -------------------------------------------------------------------
  1  net-analyzer/echoping      < 6.0.2_p434            >= 6.0.2_p434

Description
===========

A boundary error exists within the "TLS_readline()" function, which can
be exploited to overflow a global buffer by sending an overly long
encrypted HTTP reply to Echoping. Also, a similar boundary error exists
within the "SSL_readline()" function, which can be exploited in the
same manner.

Impact
======

A remote attacker could send a specially crafted HTTP reply, possibly
resulting in a Denial of Service condition.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All Echoping users should upgrade to the latest version:

  # emerge --sync
  # emerge --ask --oneshot -v ">=net-analyzer/echoping-6.0.2_p434"
