{"id":"UBUNTU-CVE-2026-57184","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, insufficient bounds checking in the `chan_ooh323` `Q.931` `information-element parser` permits an `out-of-bounds read` that may allow an unauthenticated attacker to crash Asterisk using carefully crafted `setup packets`. The `chan_ooh323` addon channel driver must be explicitly compiled and installed, which is not the default, and its port must be publicly reachable. 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.","modified":"2026-10-28T20:17:47.807538918Z","published":"2026-10-26T20:17:00Z","upstream":["CVE-2026-57184"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-57184"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-57184"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/00ebdfbc89ed160ae45a2fc0f67f36e36dae48ee"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/437d17fb13503fe9b4e72c35396f0c250d30b0f0"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/6dba027f8aea35bf3bbd89371a0cf516b13f8588"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/9c776e348374a72589cf27f635cddef45a2a2b90"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/ad4a2b3e944afd5a8e9a550bd5f62aeac8680711"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/b1284510421a29c72fc4e9a31e4b1e0666a0144f"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/20.20.1"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/21.12.3"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/22.10.1"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/23.4.1"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/certified-20.7-cert11"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/releases/tag/certified-22.8-cert3"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/security/advisories/ghsa-746q-794h-cc7f"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/tree/24.0.0-pre1"},{"type":"REPORT","url":"https://github.com/cveproject/cvelistv5/tree/main/cves/2026/57xxx/cve-2026-57184.json"},{"type":"REPORT","url":"https://nvd.nist.gov/vuln/detail/cve-2026-57184"}],"affected":[{"package":{"name":"asterisk","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/asterisk?arch=source&distro=esm-apps%2Fxenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:13.1.0~dfsg-1.1ubuntu3","1:13.1.0~dfsg-1.1ubuntu4","1:13.1.0~dfsg-1.1ubuntu4.1","1:13.1.0~dfsg-1.1ubuntu4.1+esm1"],"ecosystem_specific":{"binaries":[{"binary_name":"asterisk","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-config"},{"binary_name":"asterisk-dahdi","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_name":"asterisk-mobile","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_name":"asterisk-modules","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-mp3"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-mysql"},{"binary_name":"asterisk-ooh323","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_name":"asterisk-voicemail","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-voicemail-imapstorage"},{"binary_name":"asterisk-voicemail-odbcstorage","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_name":"asterisk-vpb","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57184.json"}},{"package":{"name":"asterisk","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/asterisk?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1:13.17.2~dfsg-1ubuntu1","1:13.17.2~dfsg-2ubuntu1","1:13.18.1~dfsg-1ubuntu1","1:13.18.3~dfsg-1ubuntu1","1:13.18.3~dfsg-1ubuntu2","1:13.18.3~dfsg-1ubuntu3","1:13.18.3~dfsg-1ubuntu4"],"ecosystem_specific":{"binaries":[{"binary_name":"asterisk","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-config"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-dahdi"},{"binary_name":"asterisk-mobile","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_name":"asterisk-modules","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-mp3"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-mysql"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-ooh323"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-tests"},{"binary_name":"asterisk-voicemail","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_name":"asterisk-voicemail-imapstorage","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_name":"asterisk-voicemail-odbcstorage","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-vpb"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57184.json"}},{"package":{"name":"asterisk","ec
