ez-ipupdate contains a format string vulnerability that could lead to execution of arbitrary code.
ez-ipupdate is a utility for updating host name information for a large number of dynamic DNS services.
Ulf Harnhammar from the Debian Security Audit Project discovered a format string vulnerability in ez-ipupdate.
An attacker could exploit this to execute arbitrary code with the permissions of the user running ez-ipupdate, which could be the root user.
There is no known workaround at this time.
All ez-ipupdate users should upgrade to the latest version:
