Synopsis
=======
Xzabite's dyndnsupdate software suffers from multiple vulnerabilities, potentially resulting in the remote execution of arbitrary code.
Background
=========
dyndnsupdate is a dyndns.org data updater written by Fredrik "xzabite" Haglund.
Affected packages
================
-------------------------------------------------------------------
Package / Vulnerable / Unaffected
-------------------------------------------------------------------
1 net-misc/dyndnsupdate lt;= 0.6.15 Vulnerable!
-------------------------------------------------------------------
NOTE: Certain packages are still vulnerable. Users should migrate to another package if one is available or wait for the existing packages to be marked stable by their architecture maintainers.
Description
==========
Toby Dickenson discovered that dyndnsupdate suffers from multiple overflows.
Impact
=====
A remote attacker, posing as a dyndns.org server, could execute arbitrary code with the rights of the user running dyndnsupdate.
Workaround
=========
There is no known workaround at this time.
Resolution
=========
Currently, there is no released version of dyndnsupdate that contains a fix for these issues. The original xzabite.org distribution site is dead, the code contains several other problems and more secure alternatives exist, such as the net-dns/ddclient package. Therefore, the dyndnsupdate package has been hard-masked prior to complete removal from Portage, and current users are advised to unmerge the package:
# emerge --unmerge net-misc/dyndnsupdate
Availability
===========
This GLSA and any updates to it are available for viewing at the Gentoo Security Website:
http://security.gentoo.org/glsa/glsa-200503-27.xml
Concerns?
========
Security is a primary focus of Gentoo Linux and ensuring the confidentiality and security of our users machines is of utmost importance to us. Any security concerns should be addressed to security@gentoo.org or alternatively, you may file a bug at http://bugs.gentoo.org.
