The SIP channel driver (chan_sip) in Asterisk Open Source 1.4.x before 1.4.11, AsteriskNOW before beta7, Asterisk Appliance Developer Kit 0.x before 0.8.0, and s800i (Asterisk Appliance) 1.x before 1.0.3 allows remote attackers to cause a denial of service (memory exhaustion) via a SIP dialog that causes a large number of history entries to be created.

Security readout for executives and security teams

This is an old Asterisk SIP denial-of-service flaw. A remote attacker could trigger excessive SIP dialog history entries, exhausting memory and potentially disrupting phone service. The public bundle does not show code execution, data theft, or confirmed active exploitation. Exposure is most plausible where legacy Asterisk SIP services are reachable by untrusted networks. Organizations no longer running the listed old versions are unlikely to be affected based on the supplied evidence. Treat as a legacy telephony availability risk. Prioritize if exposed Asterisk systems support business-critical calling, contact centers, or emergency workflows. Mitigation focus: Upgrade affected Asterisk Open Source systems to 1.4.11 or later.; Upgrade AsteriskNOW to beta7 or later if still in use.; Upgrade Asterisk Appliance Developer Kit to 0.8.0 or later..
