| <impact type="normal"> |
| <p> |
| A remote attacker, posing as a dyndns.org server, could execute |
| arbitrary code with the rights of the user running dyndnsupdate. |
| </p> |
| </impact> |
| <workaround> |
| <p> |
| There is no known workaround at this time. |
| </p> |
| </workaround> |
| <resolution> |
| <p> |
| 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: |
| </p> |
| <code> |
| # emerge --unmerge net-misc/dyndnsupdate</code> |
