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.
+------------------------------------------------------------------------+
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.
Feedback on Security Notices is welcome at <security-officer@FreeBSD.org>.
