Background ========== dyndnsupdate is a dyndns.org data updater written by Fredrik "xzabite" Haglund. Affected packages ================= ------------------------------------------------------------------- Package / Vulnerable / Unaffected ------------------------------------------------------------------- 1 net-misc/dyndnsupdate <= 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.
