Security readout for executives and security teams

This flaw can let a malicious SSL client temporarily consume the TCP connection pool used by Symantec SSL Visibility for intercepted SSL traffic. The business impact is service disruption in SSL inspection paths, not data theft based on the supplied sources. Exposure is limited to organizations operating the listed Symantec SSL Visibility versions in SSL interception or inspection workflows. Systems not running SSL Visibility, or running fixed 3.10/3.11 releases, are not indicated as affected by the supplied sources. Treat this as an operational availability risk for SSL inspection infrastructure. Prioritize remediation where SSL Visibility sits inline or supports critical traffic inspection, because disruption there may affect user connectivity or security monitoring. Mitigation focus: Inventory Symantec SSL Visibility deployments and confirm exact software versions.; Upgrade 3.10 deployments to 3.10.4.1 or later.; Upgrade 3.11 deployments to 3.11.3.1 or later..
