Shutdown of all systems on 2 february at 07:00 CET

The UPPMAX compute hall hosting EAST-1 will be partially shutdown during 2 February between 07:00 – 11:00 CET as Akademiska Hus performs work on the cooling circuit. The shutdown has been planned to coincide with our February maintenance day. We will try to provide some level of access but expect all compute capability to be unavailable until the work is completed.

If you have any questions please contact us at support@uppmax.uu.se.

Serious vulnerability in pwnkit (CVE-2021-4034)

Pwnkit is installed by default in most linux distributions, there is no permanent fix yet but there is a workaround, you can remove the suid bit from the binary using chmod 0755 /usr/bin/pkexec and that will make it impossible to exploit this bug.

  • Pkexec is installed by default on all major Linux distributions.
  • Pkexec has been vulnerable since its creation in May 2009.
  • Any unprivileged local user can exploit this vulnerability to get full root privileges.

Serious vulnerability in sudo (CVE-2021-3156)

Make sure to install the latest security updates in your instances to fix a Serious vulnerability in sudo (CVE-2021-3156) that will let any user run any command as root without entering a password.

In combination with other less severe security exploits this can in some cases be used to compromise your instances remotely.

NORTH-1 will replace the HPC2N-region.

The HP2N-region will be removed 8/2 so make sure that all instances and data are moved to either EAST-1 or WEST-1 before 7/2.

If you need assistance please send a support ticket and let us know.

We will be replacing both storage and compute and since the setup in the HPC2N region was from the pilot cloud from 2015 we unfortunately cloud not do an in place upgrade.

The new NORTH-1 region will soon be available. I will use AMD 2.5Ghz CPU:s and the boot-disks will now use flash storage.

From Pilot to Production

As SNIC Science Cloud has gone from a pilot to a production resource, the pilot regions in the cloud will be replaced new regions with production hardware.

The region at C3SE has already been replaced by the new WEST-1 region; running OpenStack Rocky on new hardware.

The other pilot cloud-regions at UPPMAX and HPC2N will soon be replaced with the EAST-1 and NORTH-1 regions.

If you are starting up new projects in the cloud we suggest that you use the WEST-1 region for now until the other regions becomes available, because otherwise you will have to migrate your workload to the new regions soon.
