{"id":"UBUNTU-CVE-2017-16872","details":"An issue was discovered in Teluu pjproject (pjlib and pjlib-util) in PJSIP before 2.7.1. Parsing the numeric header fields in a SIP message (like cseq, ttl, port, etc.) all had the potential to overflow, either causing unintended values to be captured or, if the values were subsequently converted back to strings, a buffer overrun. This will lead to a potential exploit using carefully crafted invalid values.","modified":"2026-03-25T20:37:23.301494Z","published":"2017-11-17T09:29:00Z","related":["USN-8122-1"],"upstream":["CVE-2017-16872"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-16872"},{"type":"REPORT","url":"https://trac.pjsip.org/repos/ticket/2056"},{"type":"REPORT","url":"https://trac.pjsip.org/repos/changeset/5682"},{"type":"REPORT","url":"https://trac.pjsip.org/repos/milestone/release-2.7.1"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-16872"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8122-1"}],"affected":[{"package":{"name":"pjproject","ecosystem":"Ubuntu:Pro:16.04:LTS","purl":"pkg:deb/ubuntu/pjproject@2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1?arch=source&distro=esm-apps/xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"}]}],"versions":["2.1.0.0.ast20130823-1","2.1.0.0.ast20130823-1+deb8u1build0.16.04.1"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro: https://ubuntu.com/pro","binaries":[{"binary_name":"libpj2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjlib-util2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjmedia-audiodev2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjmedia-codec2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjmedia-videodev2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjmedia2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjnath2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjproject-dev","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjsip-simple2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjsip-ua2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjsip2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"},{"binary_name":"libpjsua2","binary_version":"2.1.0.0.ast20130823-1+deb8u1ubuntu0.1~esm1"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-16872.json"}}],"schema_version":"1.7.5","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
