PPTP VPN Firewall Settings
by Drew A. Harris 12 Mar '00

12 Mar '00

I'm using the SuSE Firewall 2.0 script to set my firewall. However, I still need to manual add the following IPchains to be able to reach the VPN from my clients behind the firewall. ipchains -I input -j ACCEPT -p 17 -s [vpn server ip address] -d [my external IP] -i eth1 ipchains -I forward -j MASQ -p 47 -s 192.168.0.1/32 -d [vpn server IP] -i eth1 ipchains -I output -j ACCEPT -p 47 -s [my external IP] -d [vpn server IP] -i eth1 ipchains -I input -j ACCEPT -p 47 -s [vpn server IP] -d [my external IP] -i eth1 Is there a way to configure the firewall.rc.config file to take care of this from within the script? Thanks for your help. DREW.

Vulnerabilities in StarScheduler!
by Fred A. Miller 09 Mar '00

09 Mar '00

S.A.F.E.R. Security Bulletin 000309.EXP.1.4 __________________________________________________________ TITLE : Vulnerabilities in StarScheduler DATE : March 09, 2000 NATURE : Denial-of-Service, Remote Code Execution, Access to privileged files PLATFORMS : StarScheduler/StarOffice 5.1 DETAILS: StarOffice comes with a nice groupware server, called StarScheduler. It also includes a web server that is vulnerable to several security problems. PROBLEM: A buffer overflow exists in the StarScheduler web server (which listens on port 801), that can lead to remote execution of code and root access. Since the server dies, this is also a Denial-of-Service issue. The problem is in the way web server handles long requests. Sending a "GET /['A' x 933] HTTP/1.0" will crash the server. This web server is running as a root. Another silly problem exists in the server that allows any user to gain read access to files to which they normally don't have access to. Example: http://starscheduler_server:801/../../../../etc/shadow This will display the content of the /etc/shadow file. FIXES: No fixes are available yet. Sun has been contacted on 6th of February, but we have received no response from them. JOB OFFERS: The Relay Group is seeking security enthusiasts with a vast experience in intrusion testing, firewall/IDS configuration and other security-related fields.

FW: [suse-security] MD5 Passwords.
by |[TDP]| 08 Mar '00

08 Mar '00

Sorry.... in suse 6.3 the MD5_CRYPT_ENAB doesn't appear in /etc/login.defs and if you enable it, suse doesn't seem to change passwords to MD5... I think this feature has been removed. (in suse 6.1 i obtained md5 passwd sucessfully) I think was removed for security, MD5 is an algorithm that has collisions, however DES does not undergo problems of collisions, although it is "in theory easy to crack" by brute force. ----- Mensaje original ----- De: "Normando Marcolongo" <normando(a)studenti.ing.uniroma1.it> Para: <suse-security(a)suse.com> Enviado: martes, 07 de marzo de 2000 12:38 Asunto: [suse-security] MD5 Passwords. > > How can I enable MD5 passwords on SuSE 6.3? > > Thanks in advance! > > Normando. > > -- > Normando [enemy] Marcolongo (iW6OWQ) [] normando(a)studenti.ing.uniroma1.it > LUG Roma - IEEE S.B.

Re: [suse-security] Firewall 2.0: Samba services

Samba usually uses ports 137-139 tcp and udp, should be easy to implement a rule that fixes your problem. --- At 21:24 07.03.00 +0100, you wrote: >Hello, > >With Firewall 1.4 and 2.0 i have a problem: > >The SuSE Firewall blocking all SAMBA pakets from my internal network >:-(( >My system has 5 Networkcards.

FTP through SSH
by list 06 Mar '00

06 Mar '00

Hi! I would like to connect to my FTP Server wich is running on my Linux Server.. The Ftp server can only be reached via SSH Tunnel cause the firewall doesn't permit the packets through. The FTP server is ony for emergeny file access. I can connect to the FTP server if I do a port forward of port 21, but I the ftp server can't send me the file list cause I need an second port. How I can configure these ports? I use wu.ftpd and for example CuteFTP or FTP Voyager on Windows Machine. the FTP-server error message: 500 Illegal PORT Command 500 Can't build data connection: no PORT specified Please help me.. How I can define static ports for ftp ? thanks, chris
