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”
