Security Notice: Dirty Frag Vulnerability Mitigation

3 päeva eest

Unfortunately, a new vulnerability called Dirty Frag (https://github.com/V4bel/dirtyfrag), has been identified. CVE is pending.

HPC Center's system administrators are actively applying mitigation measures and updates across UT HPC cloud services.

IMPORTANT to all Linux virtual machine (VM) administrators: applying the necessary security measures on your VM remains essential. Living UT HPC Center's guidance is available here: https://docs.hpc.ut.ee/public/security/dirtyfrag/#blacklisting-and-removing-vulnerable-modules

Please note: users relying on kernel-based IPsec VPN/tunnel connections cannot establish an IPsec connection until the official patch is released.

The University of Tartu HPC cluster Rocket and related computing services will be unavailable on May 11 due to the cluster’s InfiniBand network upgrade. The purpose of the upgrade is to quadruple the data transfer throughput between two server rooms.

During the maintenance period, it will not be possible to run computing jobs on the following systems:
- UT HPC cluster Rocket
- Open OnDemand services (ondemand.hpc.ut.ee)
- Galaxy (galaxy.hpc.ut.ee
Access to home directories, project folders, the SFTP service, and network drives (nfs, samba) will remain available.
What to keep in mind:
- On May 9 at 07:00, the SLURM queue will be restricted; jobs running longer than 2 days will not start.
- On May 11 at 07:00, the SLURM queue will be closed for all computations.
- On May 12 at 07:00, the SLURM queue will reopen, and all services will be fully restored.
