  "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 buffer overflow through an out-of-bounds write in the \u0060Codec2\u0060 decoder caused by a \u0060floor/ceil sample-count mismatch\u0060. The \u0060codec_codec2\u0060 module must be loaded and \u0060Codec2\u0060 must be configured on the attacked endpoint. The attacker must pass SIP authentication by username/password or \u0060source IP address matching\u0060, establish a call using \u0060Codec2\u0060, and send carefully crafted \u0060Codec2\u0060 audio packets. 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.",
