Or is it actually a security update for the kernel live patch?

[opensuse-security] Will Cliqz affect Firefox versions in openSUSE?

by 686f6c6d

Greetings, I just read a (german) article[0] and official (german) Mozilla blog post[1] saying that starting next week, a small percentage of (german?) Firefox downloads will contain the "Cliqz" add-on, which is controversial, to say the least. There's already a bug report to remove it[2]. Will this in any way affect openSUSE? If so, are there plans to keep the add-on out of the openSUSE version of Firefox?

[opensuse-security] Build Service key

by linux maillist

Hello, I think the buildservice(a)opensuse.org key ( 0x6B9D6523) can be regarded a very important key. Thus, I wonder why is it not signed by the SUSE security team? It is signed by Marcus Meissner, which is fine, but shouldn´t such an important key be signed as well by the security team or at least by the openSUSE project signing key? IMHO that would grant a stronger chain of trust for that key..... -- To unsubscribe, e-mail: opensuse-security+unsubscribe(a)opensuse.org To contact the owner, e-mail: opensuse-security+owner(a)opensuse.org

[opensuse-security] Firewall on a labtop as private web / mail server

by Patrick Serru

Hello everyone, I hope I am asking on the good list. Excuse me, please, if not. This is strange, but on the 5 Leap 42.3 installations on a labtop Compaq Presario C700, the last two did me the honor to ask me the configuration of the network, and not the first three. Can anyone tell me, please, why the installation may require configuration, immediately after the choice of language and layout of the keyboard ? The choice of a minimal installation, perhaps. After this minimal installation for a text-based operation, online updating, adding to the minimum system of XOrg-X11 and tigervnc, having banned the "yast2-firewall" and "network manager" packages, the system reboots and works correctly, with wifi interfaces and Ethernet still in the desired configuration. Here is a shema of installation : ____ eth0 ____ | |<---------------->| | |desk| .-->|hub | |top | eth1 | | | |____|<--. | |____| | | 192.168.0.0 ______ eth1 | | _____ _/ \_ 198.168.1.0 | .-->| | ( ) | |modem|---->( INTERNET ) eth0 | |cable| (_ _) ____ | |_____| \______/ | |<--’ eth0 ^ |lab | | | top| wlan0 . 192.168.0.0 |____|<--.... .... Can anyone help me, please, to set up the labtop firewall, with the file /etc/sysconfig/SuSEfirewall2 ? Here is the contents of this file for my last attempt: FW_DEV_EXT="wlan0" FW_DEV_INT="eth0" FW_DEV_DMZ="" FW_ROUTE="no" FW_MASQUERADE="no" FW_MASQ_DEV="" FW_MASQ_NETS="" FW_NOMASQ_NETS="" FW_PROTECT_FROM_INT="" FW_SERVICES_EXT_TCP="http https 587 imap" FW_SERVICES_EXT_UDP="53" All other parameters contain their default values (either empty, or empty strings). My goal is to allow all the traffic on the network 192.168.1.0 (eth0) and limit that from the outside (wlan0) to http, https, 587 and imap. The labtop must of course be able to resolve domain names (DNS). I thank you for the attention you paid ti this e-mail.
