{"id":"UBUNTU-CVE-2026-57198","details":"Asterisk is an open source private branch exchange and telephony toolkit. In affected deployments, an authenticated attacker may cause a `T.140 RED` heap buffer overflow using carefully crafted packets, potentially allowing remote code execution or causing Asterisk to crash. The `chan_sip` channel driver must be installed and configured, and its `textsupport` option must be enabled; `textsupport` defaults to no. `The chan_sip driver was deprecated in Asterisk 20 and completely removed in all later versions.` 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 `chan_sip` driver was removed there.","modified":"2026-10-28T20:17:47.823769761Z","published":"2026-10-27T17:17:00Z","upstream":["CVE-2026-57198"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-57198"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-57198"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/security/advisories/GHSA-vfhr-r9x9-c687"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/0601c33d4edf8c8f221de91cead59460fb1e7180"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/111487298a954a029daae941eac423f0609b1261"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/536218a86b797996e8e8844deacc8207de373701"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/a89b61d7c756f816c7fa5327ead9e889f1531202"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/eaa108c68a32c080d7a168ef1d8bf784d5d830f4"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/eef894282be203cb9e6d8e9692e9c360a0b569b4"},{"type":"REPORT","url":"https://github.com/asterisk/asterisk/commit/fde69a1f3ff17f507a1578ae27b528f43ceb5efd"},{"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/tree/24.0.0-pre1"}],"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_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-config"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-dahdi"},{"binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1","binary_name":"asterisk-mobile"},{"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_name":"asterisk-mysql","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"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_name":"asterisk-voicemail-imapstorage","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"binary_name":"asterisk-voicemail-odbcstorage","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-vpb"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2026/UBUNTU-CVE-2026-57198.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_name":"asterisk-config","binary_version":"1:13.18.3~dfsg-1ubuntu4"},{"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_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-modules"},{"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_version":"1:13.18.3~dfsg-1ubuntu4"},{"binary_version":"1:13.18.3~dfsg-1ubuntu4","binary_name":"asterisk-voicemail"},{"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-2026-57198.json"}},{"package":{"name":"asterisk","ecosystem":"Ubuntu:20.04:LTS","purl":"pkg:deb/ubuntu/asterisk?arch=source&distro=f
