Debian GNU/Linux Advisories: interchange, xinetd, l2tpd

Debian Security Advisory DSA 150-1                     security@debian.org

Package        : interchange
Vulnerability  : illegal file exposition
Problem-Type   : remote
Debian-specific: no

A problem has been discovered in Interchange, an e-commerce and
general HTTP database display system, which can lead to an attacker
being able to read any file to which the user of the Interchange
daemon has sufficient permissions, when Interchange runs in "INET
mode" (internet domain socket).  This is not the default setting in
Debian packages, but configurable with Debconf and via configuration
file.  We also believe that this bug cannot exploited on a regular
Debian system.

This problem has been fixed by the package maintainer in version
4.8.3.20020306-1.woody.1 for the current stable distribution (woody)
and in version 4.8.6-1 for the unstable distribution (sid).  The old
stable distribution (potato) is not affected, since it doesn't ship
the Interchange system.

We recommend that you upgrade your interchange packages.

wget url
        will fetch the file for you
dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for
sources.list as given below:

apt-get update
        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the
footer to the proper configuration.

Package        : xinetd
Vulnerability  : pipe exposure
Problem-Type   : local
Debian-specific: no

Solar Designer found a vulnerability in xinetd, a replacement for the
BSD derived inetd.  File descriptors for the signal pipe introduced in
version 2.3.4 are leaked into services started from xinetd.  The
descriptors could be used to talk to xinetd resulting in crashing it
entirely.  This is usually called a denial of service.

This problem has been fixed by the package maintainer in version
2.3.4-1.2 for the current stable distribution (woody) and in version
2.3.7-1 for the unstable distribution (sid).  The old stable
distribution (potato) is not affected, since it doesn't contain the
signal pipe.

We recommend that you upgrade your xinetd packages.

dpkg -i file.deb
        will install the referenced file.

If you are using the apt-get package manager, use the line for

        will update the internal database
apt-get upgrade
        will install corrected packages

You may use an automated update by adding the resources from the

Package        : l2tpd
Vulnerability  : missing random seed
Problem-Type   : remote
Debian-specific: no

Current versions of l2tpd, a layer 2 tunneling client/server program,
forgot to initialize the random generator which made it vulnerable
since all generated random number were 100% guessable.  When dealing
with the size of the value in an attribute value pair, too many bytes
were able to be copied, which could lead into the vendor field being
overwritten.

These problems have been fixed in version 0.67-1.1 for the current
stable distribution (woody) and in version 0.68-1 for the unstable
distribution (sid).  The old stable distribution (potato) is not
affected, since it doesn't contain the l2tpd package.

We recommend that you upgrade your l2tpd packages.
