{"id":"CVE-2017-16875","details":"An issue was discovered in Teluu pjproject (pjlib and pjlib-util) in PJSIP before 2.7.1. The ioqueue component may issue a double key unregistration after an attacker initiates a socket connection with specific settings and sequences. Such double key unregistration will trigger an integer overflow, which may cause ioqueue backends to reject future key registrations.","modified":"2026-05-15T09:28:51.745877Z","published":"2017-11-17T16:29:00.190Z","references":[{"type":"ADVISORY","url":"https://trac.pjsip.org/repos/milestone/release-2.7.1"},{"type":"ADVISORY","url":"https://trac.pjsip.org/repos/ticket/2055"},{"type":"ADVISORY","url":"https://www.debian.org/security/2018/dsa-4170"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/pjsip/pjproject","events":[{"introduced":"0"},{"fixed":"ddf5bf08c48b9d8ef898f25c932d0652e9d36a52"}],"database_specific":{"cpe":"cpe:2.3:a:teluu:pjsip:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.7.1"}],"source":"CPE_FIELD"}}],"database_specific":{"source":"https://storage.googleapis.com/osv-test-cve-osv-conversion/osv-output/CVE-2017-16875.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:N/I:N/A:H"}]}
