  "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, a stack buffer overflow in the H.323 \u0060ooTrace()\u0060 trace-logging function can occur when unbounded \u0060vsprintf\u0060 writes into a fixed \u00602048-byte buffer\u0060. A remote attacker may send a carefully crafted packet that causes the Asterisk process to crash. The \u0060chan_ooh323\u0060 addon channel driver must be explicitly compiled and installed, which is not the default, and its port must be publicly reachable. 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.",
