Subject: [suse-security-announce] SuSE Security: miscellaneous


August 3rd, 2000

This notice addresses the latest security advisories from various Linux Vendors as well as private contributors.

The list of packages:

        system user account nobody
There will be SuSE Security Announcements for the packages where work is in progress as indicated in the respective section below.

* jpeg buffer overflows in netscape:

The latest version of netscape is currently being tested. SuSE netscape rpms contain efficient workarounds against some "morbid" properties of netscape - it is necessary to provide stable packages. These additions are being reworked right now.

* rpc.kstatd

The SuSE package containing rpc.kstatd (other vendors named it
rpc.statd) is called knfsd.rpm. An updated package is currently being tested.

* user `nobody's HOME directory set to / and misconfigured webservers:

SuSE Linux used to have user nobody's HOME directory set to /tmp for years. Starting with SuSE-7.0, it will be set to /var/lib/nobody . Apache, as distributed with SuSE, is configured `UserDir public_html' and is therefore not vulnerable for the http://machine/~nobody/-problem. However, we encourage admins to change this user's home using the commands

        mkdir -p /var/lib/nobody
        chown nobody.nogroup /var/lib/nobody
        usermod -d /var/lib/nobody
Make sure that you move files belonging to user nobody from the former location to the new home and that you don't rely on the old absolute path in your scripts.

* problems around pam_console:

SuSE Linux does not contain the said pam-module because it isn't included in the official pam release. The idea of it is intriguing, but we have decided not to include the module into the distribution as a consequence of the problems that accompany its use. See Linux-Mandrake Security Update Advisory ID MDKSA-2000:029.

* gpm DoS, setgid() return value:

We ship a slightly older version of gpm because of some grief with the latest versions. The vulnerabilities in gpm have been addressed to the fully necessary extent back in April 5. As mentioned above, there is no pam_console module that could change the ownerships of the gpm control socket /dev/gpmctl. By consequence, a local denial of service attack against gpm is possible. However, we believe that the most effective measure against this is userdel(8), since hogging disk space/performance, CPU, bandwidth etc is still possible in the wild even with appropriate permissions on the gpm socket.

* modes of openldap package files:

The files are installed 755 or 644. There is no problem with this package in SuSE-Linux.

* mailman problem cvsweb.cgi (TurboLinux Advisory ID#: TLSA2000016-1): kon2 (Linux-Mandrake Security Update Advisory ID: MDKSA-2000:028)

SuSE-Linux either does not contain these packages or the files therein causing the publically announced security vulnerabilities.
