Severity:	high
Title:	noip-updater: Execution of arbitrary code
Date:	01/18/2009
Bugs:	#248709
ID:	200901-12

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	Architecture(s)
net-dns/noip-updater	< 2.1.9	>= 2.1.9	All supported architectures

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"
