  "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 authenticated attacker may cause a heap-use-after-free in \u0060PJSIP TCP/SDP\u0060 handling by sending a \u0060SIP INVITE\u0060 over a connection-oriented transport and disconnecting before Asterisk responds with the \u0060200 OK\u0060. So far, the crash has only been reproduced when Asterisk is built with \u0060Address Sanitizer\u0060, which detects the issue. \u0060Address Sanitizer\u0060 is a development tool with significant performance overhead and, according to the maintainer, is not used in production systems. 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.",
