Insight
Daniel Kobras has discovered and fixed a problem in sendfiled which caused the daemon not to drop privileges as expected when sendnig notification mails. Exploiting this a local user can easily make it execute arbitrary code under root privileges. We recommend that you upgrade your sendfile packages immediately.
