Synopsis

========

 

A buffer overflow in noip-updater can lead to arbitrary code execution.

 

Background

==========

 

noip-updater is a tool used for up[censored] IP addresses of dynamic DNS

records at no-ip.com.

 

Affected packages

=================

 

-------------------------------------------------------------------

Package / Vulnerable / Unaffected

-------------------------------------------------------------------

1 net-dns/noip-updater < 2.1.9 >= 2.1.9

 

Description

===========

 

xenomuta found out that the GetNextLine() function in noip2.c misses a

length check, leading to a stack-based buffer overflow.

 

Impact

======

 

A remote attacker could exploit this vulnerability to execute arbitrary

code by sending a specially crafted HTTP message to the client. NOTE:

Successful exploitation requires a man in the middle attack, a DNS

spoofing attack or a compromise of no-ip.com servers.

 

Workaround

==========

 

There is no known workaround at this time.

 

Resolution

==========

 

All noip-updater users should upgrade to the latest version:

 

# emerge --sync

# emerge --ask --oneshot --verbose ">=net-dns/noip-updater-2.1.9"
