The remote host is missing an update for the 'postfix' package(s) announced via the USN-636-1 advisory. Sebastian Krahmer discovered that Postfix was not correctly handling mailbox ownership when dealing with Linux's implementation of hardlinking to symlinks. In certain mail spool configurations, a local attacker could exploit this to append data to arbitrary files as the root user. The default Ubuntu configuration was not vulnerable. Please install the updated package(s)
