chan_skinny.c in the Skinny (aka SCCP) channel driver in Asterisk Open Source 10.x before 10.5.1 allows remote authenticated users to cause a denial of service (NULL pointer dereference and daemon crash) by sending a Station Key Pad Button message and closing a connection in off-hook mode, a related issue to CVE-2012-2948.

Security readout for executives and security teams

This issue can let an authenticated user crash an Asterisk phone service using the Skinny/SCCP driver. The practical business impact is voice-service interruption, not data theft, based on the provided sources. Exposure appears limited to old Asterisk Open Source 10.x systems before 10.5.1 with Skinny/SCCP enabled. Likely exposed assets are Asterisk Open Source 10.x deployments earlier than 10.5.1 that use the Skinny/SCCP channel driver and allow authenticated remote Skinny clients. Prioritize remediation if the organization still runs legacy Asterisk 10.x with Skinny/SCCP. The issue can disrupt phone service, but available evidence points to authenticated denial of service rather than system takeover. Mitigation focus: Upgrade affected Asterisk Open Source 10.x systems to 10.5.1 or later.; Review AST-2012-009 for vendor-supported remediation details.; Inventory whether Skinny/SCCP is enabled on legacy Asterisk systems..
