What this means under a SharedLicense license
Your SharedLicense license itself is not affected — this is a change in LiteSpeed software, not in licensing. Update the product through its standard update channel. Licenses keep working through updates; nothing needs re-issuing or re-activating.
A heap buffer overflow was identified in LiteSpeed Web Server HTTP/2 handling. A crafted request could cause a crash or remote code execution.
