Synopsis
========
A buffer overflow in noip-updater can lead to arbitrary code execution.
Background
==========
noip-updater is a tool used for updating 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"
