8844.0. "ntalkd and NIS security questions" by MUNICH::CUZUM () Mon Feb 17 1997 05:03

Hi security-wizards,

a customer sent me some mail from CERT and wants to know which is
DIGITAL's position to following scurity holes:

1) talkd (ntalkd) -> Buffer Overrun vulnerability (intruders may be able
to execute arbitrary commands with root privileges, see AUSCERT Advisory
AA-97.01)

2) insufficiently protected NIS-domains  -> customer has been informed by 
DFN-CERT, University of Hamburg ( [email protected]) that there are some 
serious security holes concerning the protection of NIS-password-database. 
Some Unix-Systems (like Sun, HP and IBM) have released patches to protect 
the access on NIS-Servers (see /var/yp/securenets). Does anything similar 
exist for DIGITAL UNIX?

Customer needs an official statement on this security-problems. For more
information see: http://www.cert.org/ ,ftp://info.cert.org/pub/ or
e-mail me: [email protected].            

Thank-you in advance.

Regards,

Corina

I don't work for the security group, and can't help you with an "official" statement. Mike
8844.2	REF: note 2211.3 for help	BSS::BOREN	`Mon Feb 17 1997 09:27`	13
	re: .0 see note 2211.3 to get connected helping address these types of issues, posting to this (or any notesfile) may not get the help you seek. talkd - Digital's response is in the advisory noted. (in progress) nis - it's still being worked. regards rich boren

	Hi, anything new about the talkd-security hole? Regards, Corina

	I think that the patch is available. To find out for sure, or to get the "official" answer you can try contacting Henry Bone ([email protected]) who I understand is the UNIX support (USEG) contact for security related issues, or you can try contacting the SSRT directly (Rich Boren, BSS::BOREN). SSRT is the Corporate Security group responsible for coordinating the reporting and resolution of security concerns for all products, not just Digital UNIX.
