{"schema":"threatline.record/2","record":{"id":"CVE-2026-57199","aliases":["GHSA-q9fr-m7g8-6ph5"],"summary":"Asterisk: Asterisk app_sms.c copies externally controlled SMS lengths into fixed in-struct buffers","details":"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, `app_sms.c` copies externally controlled `SMS` lengths into `fixed in-struct buffers` without sufficient bounds checks, allowing an attacker to corrupt memory or crash Asterisk. The administrator must explicitly use the `SMS` dialplan application, which is useful when routing calls to or from `analog devices`, and must not have ensured that data passed to the application is valid. 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.","categories":["Unclassified"],"product":"asterisk","vendor":"asterisk","ecosystem":null,"affected_ranges":[{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-57199","source_modified_at":"2026-10-27T21:52:42.436Z","fetched_at":"2026-10-28T01:10:53.534015Z","product":"asterisk","vendor":"asterisk","versions":[{"version":"< 20.20.1","status":"affected"},{"version":">= 21.0.0-pre1, < 21.12.3","status":"affected"},{"version":">= 22.0.0-pre1, < 22.10.1","status":"affected"},{"version":">= 23.0.0-pre1, < 23.4.1","status":"affected"}],"defaultStatus":null},{"source":"CVE List","source_url":"https://www.cve.org/CVERecord?id=CVE-2026-57199","source_modified_at":"2026-10-27T21:52:42.436Z","fetched_at":"2026-10-28T01:10:53.534015Z","product":"certified-asterisk","vendor":"asterisk","versions":[{"version":"< 20.7-cert11","status":"affected"},{"version":">= 22.8-cert1-pre1, < 22.8-cert3","status":"affected"}],"defaultStatus":null}],"fixed_versions":[],"cvss":2.3,"severity":"Low","kev":{"listed":false},"epss":{"probability":null,"percentile":null,"score_date":null},"published_at":"2026-10-27T21:52:42.436Z","modified_at":"2026-10-27T21:52:42.436Z","provenance":[{"source":"CVE List","url":"https://www.cve.org/CVERecord?id=CVE-2026-57199","fetched_at":"2026-10-28T01:10:53.534015Z","source_modified_at":"2026-10-27T21:52:42.436Z"}],"sources":["CVE List"],"references":[{"source":"CVE List","url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-q9fr-m7g8-6ph5","tags":["x_refsource_CONFIRM"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/15c66022dc441ec63d7bd5f53cf7f35db72964be","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/38a2059eb77a91a6b6e76eeba5875c2b96027368","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/59b74276f24ba104d859f3f05897c9b8d835a28a","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/60f4ef3deac6b9af30519b46c13f103264038b82","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/661d6a2fc5cc7744ab9d849ed3c73ae5066386df","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/7048a3841df99e090b9d87246600373581629c98","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/commit/f46f63bd4d33665d336cf8b5998650b915222549","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3","tags":["x_refsource_MISC"]},{"source":"CVE List","url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1","tags":["x_refsource_MISC"]}],"locations":[],"motoko_assessment":{"status":"requires_architecture_review","automatic_remediation":false},"cve_state":"PUBLISHED","cvss_source":"CVE List","classification":{"method":"product-first software-layer rules","rules_version":"2.1","matched_on":null,"confidence":"unknown","reviewed":false},"change_timestamp":"2026-10-27T21:52:42.436Z","content_hash":"7e2c4b29a874129611e6b77966e96225b57693dec775e49348a64eacd4ad5222"}}
