Multiple stack consumption vulnerabilities in Asterisk Open Source 1.8.x before 1.8.19.1, 10.x before 10.11.1, and 11.x before 11.1.2; Certified Asterisk 1.8.11 before 1.8.11-cert10; and Asterisk Digiumphones 10.x-digiumphones before 10.11.1-digiumphones allow remote attackers to cause a denial of service (daemon crash) via TCP data using the (1) SIP, (2) HTTP, or (3) XMPP protocol.

Security readout for executives and security teams

This flaw can let a remote attacker crash affected Asterisk services by sending TCP data through SIP, HTTP, or XMPP. For organizations using Asterisk for voice services, the main business risk is outage, not confirmed data theft or code execution. Exposure is most likely where affected Asterisk SIP, HTTP, or XMPP TCP services are reachable from untrusted networks or broad internal networks. Treat this as a service availability risk. Prioritize remediation for internet-facing or business-critical voice systems, especially where a crash would affect customer calls, emergency routing, or support operations. Mitigation focus: Upgrade Asterisk Open Source to 1.8.19.1, 10.11.1, 11.1.2, or later.; Upgrade Certified Asterisk 1.8.11 to 1.8.11-cert10 or later.; Upgrade Digiumphones 10.x-digiumphones to 10.11.1-digiumphones or later..
