    keys that resulted in a possible Denial of Service (bsc#1216922).

## Patch Instructions:

To install this SUSE update use the SUSE recommended installation methods like
YaST online_update or "zypper patch".  
Alternatively you can run the command listed for your product:

  * SUSE Linux Enterprise High Performance Computing 15 SP1 LTSS 15-SP1  
    zypper in -t patch SUSE-SLE-Product-HPC-15-SP1-LTSS-2023-4520=1

  * SUSE Linux Enterprise Server 15 SP1 LTSS 15-SP1  
    zypper in -t patch SUSE-SLE-Product-SLES-15-SP1-LTSS-2023-4520=1

  * SUSE Linux Enterprise Server for SAP Applications 15 SP1  
    zypper in -t patch SUSE-SLE-Product-SLES_SAP-15-SP1-2023-4520=1

  * SUSE CaaS Platform 4.0  
To install this update, use the SUSE CaaS Platform 'skuba' tool. It will inform
you if it detects new updates and let you then trigger updating of the complete
cluster in a controlled way.
