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.

Encrypted filesystem on loop file
by Carlos E. R. 01 Oct '06

01 Oct '06

Hi, I'm trying to create an encrypted filesystem via Yast partitioner in SuSE 10.1, using a file mounted via the loop device. I have done this before, in fact I have two such things created under 9.3 running; but I can't (couldn't) with 10.1, it is creating a plain non encrypted filesystem instead. Or so it seemed. Looking carefully again, after several runs, I noticed that it was mounting the filesystem as plain non encrypted, but it was in fact creating an encrypted one with the appropriate entry en /etc/cryptotab instead of in /etc/fstab - whereas in 9.3 it created then in /etc/fstab instead, and in 8.x they were created in /etc/cryptotab. This criteria change is very confusing. Perhaps Yast could ask where the user wanted to define it - feature request, perhaps? It's not only a config file difference; an encrypted filesystem defined in /etc/fstab can be mounted with the command mount, but one defined in /etc/cryptotab is mounted via the command "/etc/init.d/boot.crypto start", which is less comfortable for manual mount after boot (and it mounts all devices listed, even if already mounted). /etc/cryptotab sample line: /dev/loop3 /file3 /crypta3 ext3 twofish256 acl,user_xattr /etc/fstab, the equivalent sample line: /file3 /crypta3 ext3 noauto,acl,user_xattr,loop=/dev/loop3,encryption=twofish256 0 0 Both work with the same file, I tried. I'll stay with the second one. But in 9.3 the fstab line was instead (incompatible): /file2 /crypta2 ext3 noauto,acl,user_xattr,loop=/dev/loop2,encryption=twofish256,phash=sha512,itercountk=100 Comments? Also, how would I create the equivalent encrypted filesystem manually; docus, howtos? Tks. -- Cheers, Carlos Robinson

[suse-security] Deny access to file for all applications with apparmor?
by Boyan Tabakov 01 Oct '06

01 Oct '06

Hi, I was recently going through the manuals of apparmor. As far as I could understand you can create profiles for specific executables. I was wondering, however, is it possible to create a 'generic' profile that should be applied to ANY process started. Or, what I really want to accomplish, how can I deny access to specific file for ALL processes, except, let's say one or two? If I understand the concept right, this can't be done, but let me know if I am wrong, please! -- Blade hails you...

SuSEfirewall 2 - redirect ports on internal interface to DMZ
by Dirk Enrique Seiffert 30 Sep '06

30 Sep '06

I am moving a Mailserver from the internal network to the DMZ. This move should be invisible for the enduser. Lat but not least: Some hundred mail clients are configured to consult an IP, not a name: I can't solve the issue by configuring my DNS server. This is my configuration: 200.x.x.x (public IP) | SuSEfirewall-192.168.254.1--------192.168.254.2 MailServer | 192.168.0.249 | internal network I have to access the mailserver by an IP in the 192.168.0.0/24 range. External traffic I can easily redirect with FW_FORWARD_MASQ= to an IP in the DMZ. Internal traffic I can redirect to a local port on the firewall with FW_REDIRECT. Is it possible to redirect all traffic coming on the internal interface for 192.168.0.249 to 192.168.254.2 ? Any Custom rule? I was googling quite a while to, didn't find any rule doing a forward on the internal interface. Any idea is appreciated! Thanks Enrique -- Dirk Enrique Seiffert - Lintec S.A. Ed.

Good day, I was recently fiddling around with this port forwarding issue myself. Using Susefirewall2 on a Suse 9.3 Pro allowed me to forward a port on my external IP to another port on a machine behind my firewall. However, using the same script on Novell OES (=SLES9) resulted in nothing. I then tried rinetd but dropped that again because it only forwards tcp ports, not udp. Anyway, would someone have any hints about this difference in behaviour between Suse Pro 9.3 and SLES9?

You can load additional custom rules into SuSEfirewall2 using the /etc/sysconfig/scripts/SuSEfirewall2-custom file, after enabling it in /etc/sysconfig/SuSEfirewall2. I'm not entirely sure if I understand your question correctly, but we had 3 internet connections in our house last year and did something like this (tried to simplify example so may have introduced errors. The methods for doing such things are described in full at lartc.org I suggest you read there. ------ INTERNALNIC=eth0 EXTERNALNICA=eth1 EXTERNALNICB=eth2 EXTERNALIP=0.0.0.0 #clean up for restart ip rule del fwmark 1 table interfacea.out ip rule del fwmark 2 table interfaceb.out #add rules to route packets marked with 1 with interfacea routing table #and packets marked with 2 with interfaceb routing table #you will need to have created these routing tables ip rule add fwmark 1 table interfacea.out ip rule add fwmark 2 table interfaceb.out #delete default route ip route del default #add default route through interfacea ip route add default via $externalipaddress dev $EXTERNALNICA table main #set default route for interfacea routing table through interfacea ip route del default table interfacea.out ip route add default via $EXTERNALIPA dev $EXTERNALNICA table interfacea.out #set default route for interfaceb routing table through interfaceb ip route del default table interfaceb.out ip route add default via $EXTERNALIPB dev $EXTERNALNICB table interfaceb.out #mark everything for connection 1 iptables -t mangle -A PREROUTING -i $INTERNALNIC -d 0/0 -j MARK --set-mark 1 #now mark stuff we want to go over connection2 #ssh iptables -A PREROUTING -i $INTERNALNIC -t mangle -p tcp --dport 22 -j MARK --set-mark 2 #http(s) iptables -A PREROUTING -i $INTERNALNIC -t mangle -p tcp --dport 80 -j MARK --set-mark 2 iptables -A PREROUTING -i $INTERNALNIC -t mangle -p tcp --dport 443 -j MARK --set-mark 2 #irc iptables -A PREROUTING -i $INTERNALNIC -t mangle -p tcp --dport 6667 -j MARK --set-mark 2 iptables -A PREROUTING -i $INTERNALNIC -t mangle -p tcp --dport 6669 -j MARK --set-mark 2 #ssl iptables -A PREROUTING -i $INTERNALNIC -t mangle -p tcp --dport 7070 -j MARK --set-mark 2 #freenode alternative port #put a specific machine on one connection iptables -A PREROUTING -i $INTERNALNIC -t mangle -p udp -s 192.168.0.30 -j MARK --set-mark 2 iptables -A PREROUTING -i $INTERNALNIC -t mangle -p tcp -s 192.168.0.30 -j MARK --set-mark 2

3 internet links thru firewall to windows PC
by wpc 25 Sep '06

25 Sep '06

i have 3 internet links. 2 coming through the same cisco router. and one other coming through a separate router. 1 link is purely reserved for surfing the web. while the other 2 links should be used to link to some other organisation. The two links should be accessible from one windows server inside the orgarnisation. my question is, how do i tell my SuSEFirewall to separate the traffic for the 3 links, i want the windows server to sit behind the firewall. probably in a DMZ. but it's traffic should only pass through one of the other 2 links. Also the internet traffic from the workstations should only pass through the internet link. thanks "Who the heck is General Failure, and why is he reading my harddisk?" __________________________________________________ Do You Yahoo!?
