FreeBSD-SN-02:04                                              Security Notice
                                                          The FreeBSD Project

Topic:          security issues in ports
Announced:      2002-06-19

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.
The listed vulnerabilities are not specific to FreeBSD unless
otherwise noted.

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

To upgrade a fixed port/package, perform 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.
