Unspecified vulnerability in the SIP channel driver (channels/chan_sip.c) in Asterisk 1.2.x before 1.2.13 and 1.4.x before 1.4.0-beta3 allows remote attackers to cause a denial of service (resource consumption) via unspecified vectors that result in the creation of "a real pvt structure" that uses more resources than necessary.

Security readout for executives and security teams

This CVE affects older Asterisk SIP handling and can let a remote attacker consume unnecessary server resources, causing denial of service. For organizations still running these legacy Asterisk versions, the business risk is loss or degradation of voice services rather than data theft. Exposure is most likely on legacy Asterisk deployments using the SIP channel driver, especially systems reachable by untrusted networks. The source bundle does not identify affected CPEs, distributions beyond advisories, or whether default configurations are affected. Treat this as a targeted legacy-telephony availability risk. Prioritize if Asterisk handles business-critical calling, emergency workflows, customer support, or public SIP connectivity. Otherwise, fold remediation into legacy platform cleanup. Mitigation focus: Upgrade Asterisk 1.2.x to 1.2.13 or later.; Avoid Asterisk 1.4.x builds earlier than 1.4.0-beta3.; Use vendor distribution updates where applicable..
