{"id":"UBUNTU-CVE-2017-16671","details":"A Buffer Overflow issue was discovered in Asterisk Open Source 13 before 13.18.1, 14 before 14.7.1, and 15 before 15.1.1 and Certified Asterisk 13.13 before 13.13-cert7. No size checking is done when setting the user field for Party B on a CDR. Thus, it is possible for someone to use an arbitrarily large string and write past the end of the user field storage buffer. NOTE: this is different from CVE-2017-7617, which was only about the Party A buffer.","modified":"2026-04-22T11:18:54.548459Z","published":"2017-11-09T00:29:00Z","related":["USN-4814-1"],"upstream":["CVE-2017-16671"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-16671"},{"type":"REPORT","url":"http://downloads.digium.com/pub/security/AST-2017-010.html"},{"type":"REPORT","url":"http://downloads.asterisk.org/pub/security/AST-2017-010-13.diff"},{"type":"REPORT","url":"https://issues.asterisk.org/jira/browse/ASTERISK-27337"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-16671"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4814-1"}],"affected":[{"package":{"name":"asterisk","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/asterisk@1:13.1.0~dfsg-1.1ubuntu4.1+esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"}]}],"versions":["1:13.1.0~dfsg-1.1ubuntu3","1:13.1.0~dfsg-1.1ubuntu4","1:13.1.0~dfsg-1.1ubuntu4.1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"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_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_name":"asterisk-mp3","binary_version":"1:13.1.0~dfsg-1.1ubuntu4.1+esm1"},{"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_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/2017/UBUNTU-CVE-2017-16671.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"high"}]}
