Package: ntp
Vulnerability: remote root exploit
Debian-specific: no

Przemyslaw Frasunek <venglin@FREEBSD.LUBLIN.PL> reported that ntp
daemons such as that released with Debian GNU/Linux are vulnerable to a
buffer overflow that can lead to a remote root exploit. This has been
corrected for Debian 2.2 (potato) in ntp version 4.0.99g-2potato1.

We recommend you upgrade your ntp package 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.


Debian GNU/Linux 2.2 alias potato

  Potato was released for the alpha, arm, i386, m68k, powerpc and sparc
  architectures.
