  "description": "Asterisk is an open source private branch exchange and telephony toolkit. Prior to Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3, an out-of-bounds write in \u0060chan_unistim\u0060 \u0060DIALPAGE\u0060 digit handling can overflow the \u0060phone_number\u0060 field and crash Asterisk when an attacker sends a carefully crafted incoming request packet. The \u0060chan_unistim\u0060 module must be loaded and configured with a valid \u0060UNISTIM UDP port\u0060 that the attacker can reach. The attacker must register as a configured \u0060phone MAC\u0060, or the deployment must have an equivalent \u0060production/autoprovisioning\u0060 path that allows the client to reach the main page. This issue is fixed in Asterisk 20.20.1, 21.12.3, 22.10.1, 23.4.1 and Certified Asterisk 20.7-cert11, 22.8-cert3.",
