{"id":"DEBIAN-CVE-2018-12088","details":"S3QL before 2.27 mishandles checksumming, and consequently allows replay attacks in which an attacker who controls the backend can present old versions of the filesystem metadata database as up-to-date, temporarily inject zero-valued bytes into files, or temporarily hide parts of files. This is related to the checksum_basic_mapping function.","modified":"2026-09-01T20:03:54.064777924Z","published":"2018-06-10T23:29:00.220Z","upstream":["CVE-2018-12088"],"references":[{"type":"ADVISORY","url":"https://security-tracker.debian.org/tracker/CVE-2018-12088"}],"affected":[{"package":{"name":"s3ql","ecosystem":"Debian:13","purl":"pkg:deb/debian/s3ql?arch=source&distro=trixie"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.27.1+dfsg-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-12088.json"}},{"package":{"name":"s3ql","ecosystem":"Debian:14","purl":"pkg:deb/debian/s3ql?arch=source&distro=forky"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.27.1+dfsg-1"}]}],"ecosystem_specific":{"urgency":"low"},"database_specific":{"source":"https://storage.googleapis.com/debian-osv/debian-cve-osv/DEBIAN-CVE-2018-12088.json"}}],"schema_version":"1.9.0","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"}]}
