CVE-2011-1175: tcptls.c in the TCP/TLS server in Asterisk Open Source 1.6.1.x before 1.6.1.23, 1.6.2.x before 1.6.2.17.1,...

tcptls.c in the TCP/TLS server in Asterisk Open Source 1.6.1.x before 1.6.1.23, 1.6.2.x before 1.6.2.17.1, and 1.8.x before 1.8.3.1 allows remote attackers to cause a denial of service (NULL pointer dereference and daemon crash) by establishing many short TCP sessions to services that use a certain TLS API.

Security readout for executives and security teams

This issue can let a remote party crash vulnerable Asterisk Open Source servers by repeatedly opening short TCP sessions to services using a specific TLS API. The main business risk is voice service disruption, not confirmed data theft or code execution. Exposure is most likely in legacy Asterisk Open Source deployments running 1.6.1.x before 1.6.1.23, 1.6.2.x before 1.6.2.17.1, or 1.8.x before 1.8.3.1 with TCP/TLS services reachable by untrusted networks. Treat this as a service-availability risk for legacy telephony infrastructure. Prioritize remediation where Asterisk supports business-critical voice, call-center, or emergency communication paths and is reachable from untrusted networks. Mitigation focus: Upgrade Asterisk Open Source to the fixed versions named by the advisory.; If on unsupported branches, migrate to a maintained Asterisk release.; Restrict external access to Asterisk TCP/TLS services where business requirements allow..
