                                                                FreeBSD, Inc.

Topic:          security issues in ports
Announced:      2002-03-30

I.   Introduction

Several ports in the FreeBSD Ports Collection are affected by security
issues.  These are listed below with references and affected versions.
All versions given refer to the FreeBSD port/package version numbers.

These ports are not installed by default, nor are they ``part of
FreeBSD'' as such.  The FreeBSD Ports Collection contains thousands of
third-party applications in a ready-to-install format.  FreeBSD makes
no claim about the security of these third-party applications.  See
<URL:http://www.freebsd.org/ports/> for more information about the
FreeBSD Ports Collection.

III. Upgrading Ports/Packages

Do one of the following:

1) Upgrade your Ports Collection and rebuild and reinstall the port.
Several tools are available in the Ports Collection to make this
easier.  See:
  /usr/ports/devel/portcheckout
  /usr/ports/misc/porteasy
  /usr/ports/sysutils/portupgrade

2) Deinstall the old package and install a new package obtained from

[i386]
ftp://ftp.FreeBSD.org/pub/FreeBSD/ports/i386/packages-4-stable/All/

Packages are not automatically generated for other architectures at
this time.

FreeBSD Security Notices are communications from the Security Officer
intended to inform the user community about potential security issues,
such as bugs in the third-party applications found in the Ports
Collection, which will not be addressed in a FreeBSD Security
Advisory.
