-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 ______________________________________________________________________________ SUSE Security Announcement Package: openssl Announcement ID: SUSE-SA:2006:058 Date: Thu, 28 Sep 2006 18:00:00 +0000 Affected Products: Novell Linux Desktop 9 Novell Linux POS 9 Open Enterprise Server SUSE LINUX 10.1 SUSE LINUX 10.0 SUSE LINUX 9.3 SUSE LINUX 9.2 SuSE Linux Desktop 1.0 SuSE Linux Enterprise Server 8 SuSE Linux Openexchange Server 4 SUSE LINUX Retail Solution 8 SuSE Linux School Server SuSE Linux Standard Server 8 SUSE SLED 10 SUSE SLES 10 SUSE SLES 9 UnitedLinux 1.0 Vulnerability Type: remote denial of service Severity (1-10): 7 SUSE Default Package: yes Cross-References: CVE-2006-2937, CVE-2006-2940, CVE-2006-3738 CVE-2006-4343, VU#547300, VU#386964 Content of This Advisory: 1) Security Vulnerability Resolved: several security problems in openssl 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 Several security problems were found and fixed in the OpenSSL cryptographic library. CVE-2006-3738/VU#547300: A Google security audit found a buffer overflow condition within the SSL_get_shared_ciphers() function which has been fixed. CVE-2006-4343/VU#386964: The above Google security audit also found that the OpenSSL SSLv2 client code fails to properly check for NULL which could lead to a server program using openssl to crash. CVE-2006-2937: Fix mishandling of an error condition in parsing of certain invalid ASN1 structures, which could result in an infinite loop which consumes system memory. CVE-2006-2940: Certain types of public key can take disproportionate amounts of time to process. This could be used by an attacker in a denial of service attack to cause the remote side top spend an excessive amount of time in computation. 2) Solution or Work-Around There is no known workaround, please install the update packages. 3) Special Instructions and Notes None. 4) Package Location and Checksums The preferred method for installing security updates is to use the YaST Online Update (YOU) tool. YOU detects which updates are required and automatically performs the necessary steps to verify and install them. Alternatively, download the update packages for your distribution manually and verify their integrity by the methods listed in Section 6 of this announcement. Then install the packages using the command rpm -Fhv <file.rpm> to apply the update, replacing <file.rpm> with the filename of the downloaded RPM package. x86 Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/openssl-0.9.8a-18.10.i586.… f5d7a08e60a52b7816cae88e9def7762 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/i586/openssl-devel-0.9.8a-18.10… a583491fc985dff2f3f405776fa8554a SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/openssl-0.9.7g-2.10.i… 13d07a7a3b81fdef9ba68b0f0670f14c ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/i586/openssl-devel-0.9.7g-… 1198085023a60d99ce90207b5498db45 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/openssl-0.9.7e-3.6.i58… 51606d0da43bc5c61562bb8d4679ca8b ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/i586/openssl-devel-0.9.7e-3… c6a9122fec64b5a82f433c56b602f2b5 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/openssl-0.9.7d-25.6.i5… 96b59a2af5663ae1f780626da0b5756a ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/i586/openssl-devel-0.9.7d-2… e33a86104b85919dda444b4a9901a10b Power PC Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/openssl-0.9.8a-18.10.ppc.rpm 8310266cd6da01baaf964ed8cac841c0 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/ppc/openssl-devel-0.9.8a-18.10.… 8ff4b94e685be05d00599ecc6cc939e7 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/openssl-0.9.7g-2.10.pp… 0678839057c3170dc84fab28b3dd202f ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/ppc/openssl-devel-0.9.7g-2… e86965c19538073b15c2131a04c20260 x86-64 Platform: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/openssl-0.9.8a-18.10.x86… 28dc138c088450b753fdd419c487023e ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/openssl-32bit-0.9.8a-18.… 651d62cab3c31d0bc3e18b91a4ba9ac3 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/openssl-devel-0.9.8a-18.… 2a3e98aca1aa613a58f09b39f12e84a4 ftp://ftp.suse.com/pub/suse/update/10.1/rpm/x86_64/openssl-devel-32bit-0.9.… 81bb446763424df4c18eac760e0ed80e SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/openssl-0.9.7g-2.10… 5a612bd7a6756e2926a3ef59a72fd197 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/openssl-32bit-0.9.7… 840e98707317d9cef51837a486541be7 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/openssl-devel-0.9.7… 46b1a289d445c5304001aba4417e73a9 ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/x86_64/openssl-devel-32bit… a4e2a59c151ff22ed683e115da8fce48 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/openssl-0.9.7e-3.6.x… 3bf35d8e03848aa87a662b93a8c14fe1 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/openssl-32bit-9.3-7.… 35ce818f05f655397c4b1b13ba3a93b3 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/openssl-devel-0.9.7e… dcfbcadb626de068028ac546f07ba685 ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/x86_64/openssl-devel-32bit-… da50170edc9a2596954c2453030494d6 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/openssl-0.9.7d-25.6.… 32ec53e71eefb0ebe893034ac2e552ac ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/openssl-32bit-9.2-20… 0b7706ce568832eb1b2e86bdd7cbe51d ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/openssl-devel-0.9.7d… c8671a7a77dcc5a08e2c19f9a6ff056c ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/x86_64/openssl-devel-32bit-… 2bebb0fea9579ca5e659fca63c7beac0 Sources: SUSE LINUX 10.1: ftp://ftp.suse.com/pub/suse/update/10.1/rpm/src/openssl-0.9.8a-18.10.src.rpm 2613501ca4ea03f1a79548014b13ff67 SUSE LINUX 10.0: ftp://ftp.suse.com/pub/suse/i386/update/10.0/rpm/src/openssl-0.9.7g-2.10.sr… c5b1ff892ff74af82ddbceaf757c6fb3 SUSE LINUX 9.3: ftp://ftp.suse.com/pub/suse/i386/update/9.3/rpm/src/openssl-0.9.7e-3.6.src.… f62e34422fc77343fd15a1790e6ef8d8 SUSE LINUX 9.2: ftp://ftp.suse.com/pub/suse/i386/update/9.2/rpm/src/openssl-0.9.7d-25.6.src… 8c451560ea55a3bec1b01f0b36943048 Our maintenance customers are notified individually.

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.

Detecting Brute-Force and Dictionary attacks

by Shashi Kanth Boddula

Hi All, I am looking for a good tool to detect brute-force and dictionary attacks on user accounts on a Linux system . The tool should also have the intelligence to differntiate between user mistakes and actual brute-force/dictionary attacks and reduce the false positives. SLES9/SLES10 included security tools are not helping in this case . The seccheck package functionality also not matching with my requirement. Please , anyone knows any third party security tool or any opensource security tool which solves my problem ? Thanks & Regards, Shashi Kanth,CISSP

It seems that the update overwrote the /var/lib/mailman/data/virtual-mailman file, setting it to zero length. Fortunately, I had a backup handy. Nasty! Barry -- Barry McLarnon VE3JF Ottawa, ON

Open port in SuSEfirewall2

by Terje J. Hanssen

I'm new to SuSEfirewall2 and I'm struggling to get access to my openSUSE 10.1 workstation from remote locations. The purpose is to run NX server/clients and SSH in the first phase. So far port 22 of my network router is directed to the SuSE workstation, and I've tried with YaST to enable the ssh service in the firewall. But the workstation doesn't seem to respond on remote ssh commands. Looking in /etc/sysconfig/SuSEfirewall2 the following are set: FW_SERVICES_EXT_TCP="microsoft-ds netbios-ssn ssh" FW_SERVICES_EXT_UDP="netbios-dgm netbios-ns" I'm not sure about use of required zones EXT, INT and/or DMZ? In YaST2 I could neither see a way to set both "ssh 22" as commented in the config.file? Suggestions to how to do this and to what is the preferred way to test the settings, locally and from remote? Thanks, Terje J. Hanssen

SSL client authentication with AD

by geert.van.muylem＠utimaco.be

Hi All, I'm trying to connect to an active directory (Win 2000 server) using ssl (with client authentication) The primary goal is doing that by using python-ldap (on a SuSE 10.1 environment) I get here however a strange situation that it "sometimes" works.. After some hints from the python-ldap mailing list, I tested the ssl connection with openssl, and guess what..the same result.it sometimes works.. SuSE 10.1 Openssl : 0.9.8a-16 I've tried with another version of openssl (0.9.7l) but with same result I've also tried both versions of openssl on windows and fedora core 3 with success! Anyone any idea?

geronimo user added in twice in SLES10

by shashi

Hi , I did fresh installation of SLES10 with SDK , the user geronimo added twice in /etc/passwd file . The yast users module is not working because of this issue . geronimo:x:103:105:Geronimo:/usr/share/geronimo-1.0:/bin/sh geronimo:x:114:105:Geronimo:/usr/share/geronimo-1.0:/bin/sh I think , it will be a security issue . Thanks Shashi Kanth

I've changed the password length to 15 and encryption method from DES to MD5 due to DES length limitations but when I create an user the password is truncated is still truncadet to 8 chars !
