Severity:	normal
Title:	Echoping: Buffer Overflow Vulnerabilities
Date:	06/06/2014
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	Architecture(s)
net-analyzer/echoping	< 6.0.2_p434	>= 6.0.2_p434	All supported architectures

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 --verbose
      ">=net-analyzer/echoping-6.0.2_p434"
