  "description": "Asterisk is an open source private branch exchange and telephony toolkit. In affected deployments, an authenticated attacker may cause a \u0060T.140 RED\u0060 out-of-bounds write during \u0060generation accumulation\u0060 using carefully crafted packets, potentially allowing remote code execution or causing Asterisk to crash. The \u0060chan_sip\u0060 channel driver must be installed and configured, and its \u0060textsupport\u0060 option must be enabled; \u0060textsupport\u0060 defaults to no. \u0060The chan_sip driver was deprecated in Asterisk 20 and completely removed in all later versions.\u0060 Repository comparisons verify patch containment in Asterisk 20.20.1, 21.12.3, 22.10.1 and 23.4.1, and Certified Asterisk 20.7-cert11 and 22.8-cert3. The affected release-track scope remains unresolved: structured metadata includes later release tracks even though the advisory says the required \u0060chan_sip\u0060 driver was removed there.",
