The ooh323 channel driver in Asterisk Addons 1.2.x before 1.2.9 and Asterisk-Addons 1.4.x before 1.4.7 creates a remotely accessible TCP port that is intended solely for localhost communication, and interprets some TCP application-data fields as addresses of memory to free, which allows remote attackers to cause a denial of service (daemon crash) via crafted TCP packets.

Security readout for executives and security teams

This vulnerability can let a remote attacker crash an Asterisk service using the ooh323 add-on driver. The issue is old, but exposed legacy voice systems can still face call disruption or outage. The source bundle does not show data theft, privilege escalation, or confirmed active exploitation. Likely exposure is limited to legacy Asterisk Addons deployments using the ooh323 channel driver, especially where the unintended TCP listener is reachable from untrusted networks. Products and versions beyond those named in the CVE bundle are not evidenced here. Prioritize if the organization still runs legacy Asterisk H.323 services or exposes VoIP control ports externally. For modern environments without these add-ons, urgency is low after confirming absence. The main business impact is service outage, not confirmed compromise. Mitigation focus: Upgrade Asterisk Addons 1.2.x to 1.2.9 or later.; Upgrade Asterisk-Addons 1.4.x to 1.4.7 or later.; Disable the ooh323 channel driver if it is not required..
