Security readout for executives and security teams
CVE-2011-1604 is a denial-of-service issue in older Cisco Unified Communications Manager releases. A malformed SIP message can trigger memory consumption and process failure, potentially disrupting voice services. The bundle does not show data theft or code execution. Exposure is mainly organizations still running the listed legacy CUCM versions, especially systems reachable by SIP traffic from broad internal or external networks. Modern upgraded CUCM deployments are not shown as affected in the bundle. Treat this as an availability risk to voice operations. It is most urgent for legacy CUCM environments that remain in production or accept SIP traffic across weakly controlled network boundaries. Mitigation focus: Upgrade affected CUCM branches to the fixed releases named for each version line.; Review Cisco's advisory for deployment-specific remediation guidance and caveats.; Prioritize CUCM systems that process SIP from broad or less trusted networks..
