{"id":"DEBIAN-CVE-2019-12526","details":"An issue was discovered in Squid before 4.9. URN response handling in Squid suffers from a heap-based buffer overflow. When receiving data from a remote server in response to an URN request, Squid fails to ensure that the response can fit within the buffer. This leads to attacker controlled data overflowing in the heap.","modified":"2026-09-09T07:01:12.541431852Z","published":"2019-11-26T17:15:10.843Z","upstream":["CVE-2019-12526"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2019-12526"}],"affected":[{"package":{"name":"squid","ecosystem":"Debian:12","purl":"pkg:deb/debian/squid?arch=source&distro=bookworm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2019-12526.json"}},{"package":{"name":"squid","ecosystem":"Debian:13","purl":"pkg:deb/debian/squid?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2019-12526.json"}},{"package":{"name":"squid","ecosystem":"Debian:14","purl":"pkg:deb/debian/squid?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"4.9-1"}]}],"ecosystem_specific":{"urgency":"not yet assigned"},"database_specific":{"source":"https://storage.googleapis.com/osv-test-debian-osv/debian-cve-osv/DEBIAN-CVE-2019-12526.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"}]}
