{"id":"CVE-2019-7303","details":"A vulnerability in the seccomp filters of Canonical snapd before version 2.37.4 allows a strict mode snap to insert characters into a terminal on a 64-bit host. The seccomp rules were generated to match 64-bit ioctl(2) commands on a 64-bit platform; however, the Linux kernel only uses the lower 32 bits to determine which ioctl(2) commands to run. This issue affects: Canonical snapd versions prior to 2.37.4.","modified":"2026-08-27T03:48:59.505750329Z","published":"2019-04-23T16:29:10.640Z","database_specific":{"unresolved_ranges":[{"source":"CPE_STRING","vendor_product":"canonical:ubuntu_linux","cpes":["cpe:2.3:o:canonical:ubuntu_linux:14.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:16.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:18.04:*:*:*:lts:*:*:*","cpe:2.3:o:canonical:ubuntu_linux:18.10:*:*:*:*:*:*:*"],"extracted_events":[{"introduced":"14.04"},{"last_affected":"14.04"},{"introduced":"16.04"},{"last_affected":"16.04"},{"introduced":"18.04"},{"last_affected":"18.04"},{"introduced":"18.10"},{"last_affected":"18.10"}]}]},"references":[{"type":"ADVISORY","url":"https://usn.ubuntu.com/3917-1/"},{"type":"EVIDENCE","url":"https://www.exploit-db.com/exploits/46594"}],"affected":[{"ranges":[{"type":"GIT","repo":"https://github.com/canonical/snapd","events":[{"introduced":"0"},{"fixed":"af063cbb045a1e232bfb5131683657f78b0cd7ad"}],"database_specific":{"cpe":"cpe:2.3:a:canonical:snapd:*:*:*:*:*:*:*:*","extracted_events":[{"introduced":"0"},{"fixed":"2.37.4"}],"source":"CPE_RANGE"}}],"versions":["2.37.3","2.37.2","2.37.1","2.37","untagged-ec50ee5bfb45daefc236","2.15.2","2.15","2.14.2.16.04","2.14.1","2.14","2.13","2.12","2.11","2.0.10","2.0.9","2.0.8","2.0.7","2.0.6","2.0.5","2.0.4","2.0.3","2.0","1.9.4","1.9.3","1.9.2","1.9.1","1.9","ppa","1.7.3+20160310ubuntu1","1.7.3+20160308ubuntu1","1.7.3+20160303ubuntu4","1.7.3+20160303ubuntu3","1.7.3+20160303ubuntu2","1.7.3+20160303ubuntu1","1.7.3+20160225ubuntu1","1.7.2+20160223ubuntu1","1.7.2+20160204ubuntu1","1.7.2+20160113ubuntu1","1.7.2ubuntu1","1.7ubuntu1","1.6ubuntu1","1.5ubuntu1","1.4ubuntu1","1.3ubuntu1","1.2-0ubuntu1","1.1.2-0ubuntu1","1.1.1-0ubuntu1","1.1-0ubuntu1","1.0.1-0ubuntu1","1.0-0ubuntu1"],"database_specific":{"source":"https://storage.googleapis.com/cve-osv-conversion/osv-output/CVE-2019-7303.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:N/I:H/A:N"}]}
