A heap buffer overflow in the format_ogg_speex module allows an attacker to cause a Denial of Service (DoS) or potentially achieve arbitrary code execution. This issue occurs when Asterisk reads a corrupted Speex audio file, triggering an unbounded memory copy operation. An attacker who can provide a malicious audio file and induce Asterisk to play it can crash the application or compromise the system."], "name": "CVE-2026-57197", "public_date": "2026-10-27T16:35:59Z", "references": ["https://www.cve.org/CVERecord?id=CVE-2026-57197\nhttps://nvd.nist.gov/vuln/detail/CVE-2026-57197\nhttps://github.com/asterisk/asterisk/commit/0a2c1d9e910f7c4dfffa05e328accb8a96990df8\nhttps://github.com/asterisk/asterisk/commit/0e6d761ed83f1671632c91805252767eae85e1a2\nhttps://github.com/asterisk/asterisk/commit/1cf189549994e0898954c814ce5a023cd969f1db\nhttps://github.com/asterisk/asterisk/commit/29026ece6fdd1834bb8f49c013ef163745ff2bbd\nhttps://github.com/asterisk/asterisk/commit/336ebe762bf6dfaf279796700de8ab51f7acd2f3\nhttps://github.com/asterisk/asterisk/commit/ccec146953b5e13043a36663af84e5a50ca633a6\nhttps://github.com/asterisk/asterisk/commit/dbcf38933866f0ddd023bc1814a78d4c750b0809\nhttps://github.com/asterisk/asterisk/releases/tag/20.20.1\nhttps://github.com/asterisk/asterisk/releases/tag/21.12.3\nhttps://github.com/asterisk/asterisk/releases/tag/22.10.1\nhttps://github.com/asterisk/asterisk/releases/tag/23.4.1\nhttps://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11\nhttps://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3\nhttps://github.com/asterisk/asterisk/security/advisories/GHSA-8jhw-m2hg-vp3h\nhttps://github.com/asterisk/asterisk/tree/24.0.0-pre1"], "statement": "This vulnerability is rated as Important because an out-of-bounds write during audio parsing can lead to service crashes or potential arbitrary code execution, though exploitation is constrained by the prerequisite of placing a crafted media file on the host.
