-----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.

[opensuse-security] Conecting from Linux to MS VPN server

by Branislav Klocok

Hi all, I am not sure whether this is the right place to ask, but lets try.... In my previous job we use to have a suse linux as default desktop on our machines. Few months ago I have changed my job and I would like to use Linux on my notebook. Unfortunately I can not expect any help from our IT department.... So I have received a working windows xp notebook with preinstalled software on it (including windows vpn client L2TP). I have installed on one part of the hard disk SUSE 10.1 and made a basic setup. In the office all works fine, but since travel a lot a need to access the network via VPN in order to download my emails. Can somebody give me a hint how to proceed?

[opensuse-security] Security report from rkhunter on default install of openSUSE 10.2

by Pavel Chalupa

Hi, is there anybody who can explain the security report generated by rkhunter? At first: default install includes SSHD with remote root login allow, all users remote login allowed, SSH protocol 1 allowed... during install is SSH disallowed, but SSHD runnig after install... At second: after some online updates, I tried to run rkhunter and its reporting invisible /dev/tmpblablabla... and some two other files corresponding with this one... this was too confusing and I killed this by command rm /dev/tmpblabla... I have no idea what it was, but rkhunter reported that system is infected... I have no backup of this, but the machine still runnig and I can make some investigation, but I don't know how to do it. Does the second problem means, that openSUSE 10.2 has security hole in default install and fresh installation can be exploited remotly during/after online update, when making fresh install? Or one of the online repositories includes package with backdoor? Any suggestions? Pavel Chalupa

Re: [opensuse-security] problems with smbmount and OSS10.2

If you need to do this as a normal user you should use mount.cifs directly instead of mount -t cifs, and do a chmod +s on mount.cifs, too, just like you had to do on smbmount. For further info, please read "man mount.cifs". Now, why the removal of smbfs isn't mentioned in the relase notes is a mystery. I finally found a comment in the kernel changelog: * ons 30 aug 2006 - gregkh(a)suse.de - Disable CONFIG_SMB_FS CIFS is now the way to go. The samba team is working on the migration tools for the upgrade issues. ...but where the "migration tools" can be found is still a mystery to me. /Lennart onsdag 27 december 2006 20:00 skrev Remington Router: > You might try the same thing with CIFS: > > mount -t cifs -o ip=192.168.33.35,username=franky //franky/share /mnt > > On Wed, 27 Dec 2006 19:01:41 +0100, Tolmino <gratis(a)tolmino.it> wrote: > > Hi, after oss10.2 installation i have tried to mount a smb filesystem: > > > > mount -t smbfs -o ip=192.168.33.35,username=franky //franky/share /mnt > > > > but i have received this message after i have inserted password > > > > Suse Kernel don't support smb filesystem!!! > > > > Do i must recompile? > > thanks > > --------------------------------------------------------------------- > > To unsubscribe, e-mail: opensuse-security+unsubscribe(a)opensuse.org > > For additional commands, e-mail: opensuse-security+help(a)opensuse.org > > -- > Remmy Router > > --------------------------------------------------------------------- > To unsubscribe, e-mail: opensuse-security+unsubscribe(a)opensuse.org > For additional commands, e-mail: opensuse-security+help(a)opensuse.org -- !++ !

[opensuse-security] snort in SLES9 and SLES10

by shashi

In SLES9 SP3, and in SLES10 SuSE:/usr/share/doc/packages/snort # pwd /usr/share/doc/packages/snort SuSE:/usr/share/doc/packages/snort # du -h *.bz2 4.0K ACID-0.9.6b21.tar.bz2 4.0K Guardian.tar.bz2 4.0K Net-SnortLog-0.1.tar.bz2 4.0K Spade-092200.1.tar.bz2 4.0K passiveOS.tar.bz2 4.0K snortdb-extra.bz2 4.0K snortnet.tar.bz2 4.0K snortwatch-0.7.tar.bz2 SuSE:/usr/share/doc/packages/snort # Why Novell/SuSE is giving empty files of snort add-ons ? When i first saw, i thought Novell is giving tested versions of snort add-ons which perfectly works with bundled snort version. But, when i try to configure ACID in SLES9 SP3, i discovered that it is a empty file. Then i immediately look into SLES10, and in SLES10 too those files are empty files. Is it a mistake from Novell/SuSE side ? or is there any reason/purpose ?

[opensuse-security] Restrict ssh command execution

by Boyan Tabakov

Hi, Is it possible to restrict certain users to executing only one specific command on the server with ssh? No interactive login should be allowed and no other commands should be accepted. If possible - how? Didn't see any options in sshd_config that looked promising... One think that came to mind is using the shell field in the /etc/passwd file (setting it to some custom script). Any other ideas? -- Blade hails you... Join my soul the Hunter in the sky --Nightwish
