Package        : sendfile
Vulnerability  : broken privileges dropping, broken tempfile
Type           : local root exploit
Debian-specific: no

Colin Phipps and Daniel Kobras discovered and fixed several serious
bugs in the saft daemon `sendfiled' which caused it to drop privileges
incorrectly.  Exploiting this a local user can easily make it execute
arbitrary code under root privileges.

We recommend you upgrade your sendfile packages immediately.

wget url
	will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

You may use an automated update by adding the resources from the
footer to the proper configuration.
