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"
