sendfile
Vulnerable:

More information:
Daniel Kobras has discovered and fixed a problem in sendfiled which caused the daemon not to drop privileges as expected when sending notification mails. Exploiting this, a local user can easily make it execute arbitrary code under root privileges.

We recommend that you upgrade your sendfile package immediately.

Fixed in:
