Hi Please take a look at this ipchains firewall. how secure is this? What could be done better (except that the code could have more variables)?

Crypto packages for 7.0

-----BEGIN PGP SIGNED MESSAGE----- Dear reader, Many customers have asked to publish the packages of the SuSE-7.0 distribution that are not included in the US version due to US crypto regulations.

SuSE Security Announcement: syslogd/klogd
by Roman Drahtmueller 26 Sep '00

26 Sep '00

-----BEGIN PGP SIGNED MESSAGE----- ______________________________________________________________________________ SuSE Security Announcement Package: syslogd/klogd Date: Wednesday, September 20th, 2000 03:00 MEST Affected SuSE versions: 6.1 6.2, 6.3, 6.4, 7.0 Vulnerability Type: local DoS, possible root compromise Severity (1-10): 5 SuSE default package: yes Other affected systems: Linux systems, possibly unix systems Content of this advisory: 1) security vulnerability resolved: syslogd/klogd problem description, discussion, solution and upgrade information 2) pending vulnerabilities, solutions, workarounds 3) standard appendix (further information) ______________________________________________________________________________ 1) problem description, brief discussion, solution, upgrade information The syslogd package consists of two daemons that are being launched upon system startup: klogd and syslogd. The former collects kernel messages and passes them on to the syslog(3) facility. syslogd will pick up the logging messages and write them to the logfiles as specified by the syslogd configuration file /etc/syslog.conf. Errors in both the klogd and the syslogd can cause both daemons do die when specially designed strings get passed to the kernel by the user, eg. with a malformed structure in a system call. These errors have been discovered by Jouko Pynnönen, Solar Designer, a fix for one of the bugs has been provided by Daniel Jacobowitz. There is currently no known way to exploit these bugs with an effect other than a DoS (Denial of Service) of the syslog/klog service. Since it may be possible to execute arbitrary code as a result of a buffer overflow, administrators should consider applying the patches as soon as possible. Also, logging messages resulting from firewall rules in the kernel can get lost if the daemon does not pick them up. Efficient temporary countermeasures against these attacks other than package upgrade do not exist. Download the update package from locations desribed below and install the package with the command `rpm -Fhv file.rpm'. The md5sum for each file is in the line below. You can verify the integrity of the rpm files using the command `rpm --checksig --nogpg file.rpm', independently from the md5 signatures below. i386 Intel Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/i386/update/7.0/a1/syslogd-1.3.33-161.i386.rpm 284b1975cda65cd6ed5ce65672706e19 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/7.0/zq1/syslogd-1.3.33-161.src.rpm 49c7a171753171f4e6fd772453d46a93 SuSE-6.4 ftp://ftp.suse.com/pub/suse/i386/update/6.4/a1/syslogd-1.3.33-161.i386.rpm cb89ed419b0c9dbf7c66191a58606920 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.4/zq1/syslogd-1.3.33-161.src.rpm 33686198aa6412401b0056241829aae0 SuSE-6.3 ftp://ftp.suse.com/pub/suse/i386/update/6.3/a1/syslogd-1.3.33-161.i386.rpm af5e43976fb9814e1f5d626e16c2d176 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.3/zq1/syslogd-1.3.33-161.src.rpm 1e821f6fda1f471d36e9b4990aa496b4 SuSE-6.2 ftp://ftp.suse.com/pub/suse/i386/update/6.2/a1/syslogd-1.3.33-9.i386.rpm fc29df9455288f40eb1e8dbd0f47d5b3 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.2/zq1/syslogd-1.3.33-9.src.rpm ae980989a754e6bf85de9dd60676b321 SuSE-6.1 ftp://ftp.suse.com/pub/suse/i386/update/6.1/a1/syslogd-1.3.33-161.i386.rpm c8d23ec6c3a9f944c15d6e12ffebc66f source rpm: ftp://ftp.suse.com/pub/suse/i386/update/6.1/zq1/syslogd-1.3.33-161.src.rpm b0329c20caf1d1d427da9961240732f5 SuSE-5.3 ftp://ftp.suse.com/pub/suse/i386/update/5.3/a1/syslogd-1.3.33-9.i386.rpm 3104e26a8b474e215ed703b7c4d48888 source rpm: ftp://ftp.suse.com/pub/suse/i386/update/5.3/zq1/syslogd-1.3.33-9.src.rpm 09c9539df1c4225d2366a2a860b01dbb Sparc Platform: SuSE-7.0 ftp://ftp.suse.com/pub/suse/sparc/update/7.0/a1/syslogd-1.3.33-161.sparc.rpm 38bb40e8bdfd55387f0e25407d4e5cbd source rpm: ftp://ftp.suse.com/pub/suse/sparc/update/7.0/zq1/syslogd-1.3.33-161.src.rpm 2017cbca57305092c0a912b77c2411dd AXP Alpha Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/axp/update/6.4/a1/syslogd-1.3.33-162.alpha.rpm 419ea3172f4532f77c4fc5907de345f2 source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.4/zq1/syslogd-1.3.33-162.src.rpm 44cb992c94dffff0d31b65a0938fc1cc SuSE-6.3 ftp://ftp.suse.com/pub/suse/axp/update/6.3/a1/syslogd-1.3.33-161.alpha.rpm 84cfb8fa2e471baadf96eae1d3be1d0a source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.3/zq1/syslogd-1.3.33-161.src.rpm 23ee4562c993de6943cead4878e73259 SuSE-6.1 ftp://ftp.suse.com/pub/suse/axp/update/6.1/a1/syslogd-1.3.33-161.alpha.rpm 3b04489436b536d3d2e4b4bec6bc5ced source rpm: ftp://ftp.suse.com/pub/suse/axp/update/6.1/zq1/syslogd-1.3.33-161.src.rpm ab7edad2685d8d820b0f72b470048e81 PPC Power PC Platform: SuSE-6.4 ftp://ftp.suse.com/pub/suse/ppc/update/6.4/a1/syslogd-1.3.33-161.ppc.rpm 9d588d1d4614d173b60746ae74fc6046 source rpm: ftp://ftp.suse.com/pub/suse/ppc/update/6.4/zq1/syslogd-1.3.33-161.src.rpm eae3b0cd9b7de4ded453e9151b722b0e ______________________________________________________________________________ 2) Pending vulnerabilities in SuSE Distributions and Workarounds: This is the updated list of currently known security problems.

pam_passwdqc for SuSE?
by Nix 25 Sep '00

25 Sep '00

Any chance of including this as an rpm on the SuSE ftp site? and with new versions of SuSE? I know YaST checks with john, but something that plugs into PAM is pretty cool.

Package updating ...
by Markus Gaugusch 25 Sep '00

25 Sep '00

I have some machines running (of course ;) SuSE Linux, but there is one thing that would be really cool: when an advisory comes out, I have to update every single machine. ok, this is not so bad, because there are things to do manually (restarting daemons, etc.), BUT a tool doing the following would make it much easier for me to keep up-to-date (because sometimes i forget to update a machine, or don't update all packages): The tool should read a list of all current rpm's from a website (maybe two websites: security important and general updates). Of course version numbers must be given!) Then it compares the version numbers from the homepage with the RPM-Database. The output should be a list of download urls with the missing (newer) packages. You could also give a parameter like "--source ftp://gd.tuwien.ac.at:2100/suse/i386" giving the primary download source (so ftp.suse.com doesn't get overloaded). bye!
