-----BEGIN PGP SIGNED MESSAGE----- August 3rd, 2000 This notice addresses the latest security advisories from various Linux Vendors as well as private contributors. The list of packages: netscape knfsd system user account nobody pam_console gpm openldap mailman cvsweb.cgi kon2 <p>There will be SuSE Security Announcements for the packages where work is in progress as indicated in the respective section below. <p><p>* 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. _________________________________________________________________________ <p><p>Regards, Roman Drahtmüller. - -- - - | Roman Drahtmüller <draht@suse.de> // "Caution: Cape does | SuSE GmbH - Security Phone: // not enable user to fly." | Nürnberg, Germany +49-911-740530 // (Batman Costume warning label) | - - Type Bits/KeyID Date User ID pub 2048/3D25D3D9 1999/03/06 SuSE Security Team <security@suse.de> - -----BEGIN PGP PUBLIC KEY BLOCK----- Version: 2.6.3i mQENAzbhLQQAAAEIAKAkXHe0lWRBXLpn38hMHy03F0I4Sszmoc8aaKJrhfhyMlOA BqvklPLE2f9UrI4Xc860gH79ZREwAgPt0pi6+SleNFLNcNFAuuHMLQOOsaMFatbz JR9i4m/lf6q929YROu5zB48rBAlcfTm+IBbijaEdnqpwGib45wE/Cfy6FAttBHQh 1Kp+r/jPbf1mYAvljUfHKuvbg8t2EIQz/5yGp+n5trn9pElfQO2cRBq8LFpf1l+U P7EKjFmlOq+Gs/fF98/dP3DfniSd78LQPq5vp8RL8nr/o2i7jkAQ33m4f1wOBWd+ cZovrKXYlXiR+Bf7m2hpZo+/sAzhd7LmAD0l09kABRG0JVN1U0UgU2VjdXJpdHkg VGVhbSA8c2VjdXJpdHlAc3VzZS5kZT6JARUDBRA24S1H5Fiyh7HKPEUBAVcOB/9b yHYji1/+4Xc2GhvXK0FSJN0MGgeXgW47yxDL7gmR4mNgjlIOUHZj0PEpVjWepOJ7 tQS3L9oP6cpj1Fj/XxuLbkp5VCQ61hpt54coQAvYrnT9rtWEGN+xmwejT1WmYmDJ xG+EGBXKr+XP69oIUl1E2JO3rXeklulgjqRKos4cdXKgyjWZ7CP9V9daRXDtje63 Om8gwSdU/nCvhdRIWp/Vwbf7Ia8iZr9OJ5YuQl0DBG4qmGDDrvImgPAFkYFzwlqo choXFQ9y0YVCV41DnR+GYhwl2qBd81T8aXhihEGPIgaw3g8gd8B5o6mPVgl+nJqI BkEYGBusiag2pS6qwznZiQEVAwUQNuEtBHey5gA9JdPZAQFtOAf+KVh939b0J94u v/kpg4xs1LthlhquhbHcKNoVTNspugiC3qMPyvSX4XcBr2PC0cVkS4Z9PY9iCfT+ x9WM96g39dAF+le2CCx7XISk9XXJ4ApEy5g4AuK7NYgAJd39PPbERgWnxjxir9g0 Ix30dS30bW39D+3NPU5Ho9TD/B7UDFvYT5AWHl3MGwo3a1RhTs6sfgL7yQ3U+mvq MkTExZb5mfN1FeaYKMopoI4VpzNVeGxQWIz67VjJHVyUlF20ekOz4kWVgsxkc8G2 saqZd6yv2EwqYTi8BDAduweP33KrQc4KDDommQNDOXxaKOeCoESIdM4p7Esdjq1o L0oixF12Cg== =pIeS - -----END PGP PUBLIC KEY BLOCK----- -----BEGIN PGP SIGNATURE----- Version: 2.6.3i Charset: noconv iQEVAwUBOYnpPney5gA9JdPZAQEUOQf8DKKIHhn7oUvTW5Ol7gww2/aIwXmG2e5c 4iKyQgGoU94YZURlGxRRI5Zf1Yydfj8JrKiUvnwxRCcQF2WWWCWkGNqQkJzt+c00 BiEyU16fklxMV17JeI6zmb9rTrne0JftjAycAPubzYeDpheVDbmPtGvotanRwVUn j2zaE3uLIBjie2025q8nZnYeTylXua4ulnTW0+PFDZnWgyxCMXvvu/1Lsf715vi6 1M6L78IlYkng5OV4OTeBVY5gm7sdy3eg/CQ/FiEHmIDgI33ywRVGQhXqhpp3QOrX OA7UoIl6xAhNHBEX9lSPwNpfFaTsQrEAWVbihnzFYSLlBz3kxd1jdQ== =5DM/ -----END PGP SIGNATURE-----
