Package: ntop
Vulnerability: remote file exploit
Debian-specific: no
Vulnerable: yes

Using ntop to distribute network traffic through the network,
i.e. running ntop as webserver, it is possible to access arbitrary
files on the local filesystem.  Since ntop runs as root uid, guess
what that means, even /etc/shadow got unsecured.

Since ntop comes with its own simple web server this problem is not a
result of another webserver insecurity.

Debian GNU/Linux 2.1 alias slink
- --------------------------------

  The "ntop" package is not a part of Debian 2.1.  No fix is necessary.

Debian 2.2 alias potato
- -----------------------

  This version of Debian is not yet released.  Fixes are currently
  available for Alpha, ARM, Intel ia32, Motorola 680x0, PowerPC and
  the Sun Sparc architecture.
