Re: [suse-security] Intrusion spyware malware key stroke detection
by Martin 22 Feb '06

22 Feb '06

I use suse 9.3 pro on home network. Boxed retail DVD set. Suse firewall. Security updates are current. KDE Konqueror and / or Firefox. Comcast cable internet service provider. No alias. Everyday I am seeing spam email which is a reflection of complex sensitive key word phrases I had typed into google just a few days previously. What are the security implications of this? How do I configure what I have to stop this? What additional measures might be appropriate? Is this spying for commercial purposes or could it be US Government spying? The linux network worm? Aliasing? Fire wall configuration? Stop always connected cable internet and go back to using on demand dialup.? My first reactions are to look into aliasing. Or go back to on demand dialup. But if keystrokes are being detected then there is no security. Very alarming. Thanks to any who can help Martin

SUSE Security Announcement: CASA remote code execution (SUSE-SA:2006:010)
by Marcus Meissner 22 Feb '06

22 Feb '06

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: CASA Announcement ID: SUSE-SA:2006:010 Date: Wed, 22 Feb 2006 12:00:00 +0000 Affected Products: Novell Linux Desktop 9 Open Enterprise Server 1 Vulnerability Type: remote code execution Severity (1-10): 10 SUSE Default Package: yes Cross-References: CVE-2006-0736 Content of This Advisory: 1) Security Vulnerability Resolved: remote root exploit in CASA PAM handler Problem Description 2) Solution or Work-Around 3) Special Instructions and Notes 4) Package Location and Checksums 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. 6) Authenticity Verification and Additional Information ______________________________________________________________________________ 1) Problem Description and Brief Discussion This update fixes a remotely exploitable stack buffer overflow in the pam_micasa authentication module. Since this module is added to /etc/pam.d/sshd automatically on installation of CASA it was possible for remote attackers to gain root access to any machine with CASA installed. This is tracked by the Mitre CVE ID CVE-2006-0736. 2) Solution or Work-Around Upgrade to the fixed packages. You can also deinstall CASA by doing: rpm -e CASA CASA-gui CASA-devel 3) Special Instructions and Notes None. 4) Package Location and Checksums The preferred method for installing security updates on Novell Linux Desktop 9 and Open Enterprise Server 1 is to use the Redcarpet frontends, either via the GUI interface or the "rug" commandline frontend. The packages are also offered for installation from the maintenance web: http://support.novell.com/cgi-bin/search/searchtid.cgi?psdb/eb79800a3d8a5cb… ______________________________________________________________________________ 5) Pending Vulnerabilities, Solutions, and Work-Arounds: See SUSE Security Summary Report. ______________________________________________________________________________ 6) Authenticity Verification and Additional Information - Announcement authenticity verification: SUSE security announcements are published via mailing lists and on Web sites. The authenticity and integrity of a SUSE security announcement is guaranteed by a cryptographic signature in each announcement. All SUSE security announcements are published with a valid signature. To verify the signature of the announcement, save it as text into a file and run the command gpg --verify <file> replacing <file> with the name of the file where you saved the announcement. The output for a valid signature looks like: gpg: Signature made <DATE> using RSA key ID 3D25D3D9 gpg: Good signature from "SuSE Security Team <security(a)suse.de>" where <DATE> is replaced by the date the document was signed. If the security team's key is not contained in your key ring, you can import it from the first installation CD. To import the key, use the command gpg --import gpg-pubkey-3d25d3d9-36e12d04.asc - Package authenticity verification: SUSE update packages are available on many mirror FTP servers all over the world. While this service is considered valuable and important to the free and open source software community, the authenticity and the integrity of a package needs to be verified to ensure that it has not been tampered with. There are two verification methods that can be used independently from each other to prove the authenticity of a downloaded file or RPM package: 1) Using the internal gpg signatures of the rpm package 2) MD5 checksums as provided in this announcement 1) The internal rpm package signatures provide an easy way to verify the authenticity of an RPM package. Use the command rpm -v --checksig <file.rpm> to verify the signature of the package, replacing <file.rpm> with the filename of the RPM package downloaded. The package is unmodified if it contains a valid signature from build(a)suse.de with the key ID 9C800ACA. This key is automatically imported into the RPM database (on RPMv4-based distributions) and the gpg key ring of 'root' during installation. You can also find it on the first installation CD and at the end of this announcement. 2) If you need an alternative means of verification, use the md5sum command to verify the authenticity of the packages. Execute the command md5sum <filename.rpm> after you downloaded the file from a SUSE FTP server or its mirrors. Then compare the resulting md5sum with the one that is listed in the SUSE security announcement. Because the announcement containing the checksums is cryptographically signed (by security(a)suse.de), the checksums show proof of the authenticity of the package if the signature of the announcement is valid. Note that the md5 sums published in the SUSE Security Announcements are valid for the respective packages only. Newer versions of these packages cannot be verified. - SUSE runs two security mailing lists to which any interested party may subscribe: suse-security(a)suse.com - General Linux and SUSE security discussion.

I think the settings are right (othervice YaST will complain). It's just not available from Guru, PackMan or the GM-Extra from SUSE. Can you check from which repository you have it installed from? > You could also search for it in http://rpm.pbone.net/ Or register at nessus.org - thanks Keith - (there is newer version there too), but I'm still far more confortable in installing software from YaST than by doing it manually :-) And I'm slightly surprised that nessus is not in any of the YaST repositories I listed. After all, I think it's one of the leading tools, or have I missunderstod something...? (I think NMAP is great, even though the KDE-GUI from Guru didn't work for reports, but I just finds open ports and doesn't do anything beyond that.) -- HG.

Hi list, I use Suse 10 with postfix - amavis-new and clamav. I want to define a spam control policy but I have same problem. First of all if i have a mail that has a score of 5.64 it arrives to the mailbox without adding flags in the header or rewriting subject. Second amavis doesn't do the rbl check.

OpenSSH scp command expansion bug - is it local or remote?
by David Corking 14 Feb '06

14 Feb '06

1. Thanks for the patch and announcement today : SUSE-SA:2006:008 2. There seems to have been a co-ordinated disclosure and release of patches for CVE-2006-0225 on January 25. Why did SuSE (and Debian) not participate in that? Did the other vendors choose not to co-ordinate with SuSE (and Debian) ? 3. I have now avidly read the majorr reports of CVE-2006-0225, most of whom classify it as low priority, and all classify as local. It seems to me, from the reports I read, that it is a local privilege escalation that allows an authenticated scp user to execute arbitrary shell commands, even if they have scp-only privileges. I am not in any way a skilled penetration tester - so I have to make a judgement based on what I read. Have I misunderstood the other reports, or have the other reports got it right, or have SuSE discovered something new that makes it indeed a *remote* vulnerability? David

Hi there, Sorry for opening a new thread instead of following the one started a days ago about this matter. I just have joined this list today and cannot reply to that message. Said that, I would like to confirm the bug reported from Carlos E.R. about the security update available on YOU to correct a bug of Hylafax. In fact, this update have broken the notify script so no notification is sent now when a new fax arrives. I am running SUSE Linux 10.0 (x86_64) and Hylafax 4.2.1. Greetings, -- Camaleón

UDP encapsulation in Suse 10?

Hello all, I am successful in setting up IPSec with preshared keys (both transport and tunnel ) using racoon between two Suse Linux 10 machines. I would like to know if there is already UDP encapsualation capability integrated with Freeswan implementation on Suse Linux ( kernel release 2.6.13-15). Because the README files for NAT traversal says, I need to patch up the kernel. Do I have to do it and if yes, where to get the patches from, kindly point me to the right direction. If anyone has any more info, a how to or related info that can be shared, would be very much helpful, thanks and regards, pj

File and folder access auditing, how?
by HG 08 Feb '06

08 Feb '06

Hello! Is it possible to set up file and folder access auditing on SuSE 9.2 or later (10.0)? If so, how would one do that? I have some sensitive information now on SuSE 9.2 (that might be updated to 10.X) and I'm looking for something similar to what I had in Windows. I want to have a log somewhere that would indicate who has used or tried to use the sensitive information. -- HG.
