Gentoo Linux Security Advisory

Title: noip-updater: Execution of arbitrary code (GLSA 200901-12)
Severity: high
Exploitable: remote
Date: January 18, 2009
Bug(s): #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: net-dns/noip-updater
Vulnerable: < 2.1.9
Unaffected: >= 2.1.9
Architectures: 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:
Code:
# emerge --sync
# emerge --ask --oneshot --verbose ">=net-dns/noip-updater-2.1.9"
