{"id":"UBUNTU-CVE-2026-34982","details":"Vim is an open source, command line text editor. Prior to version 9.2.0276, a modeline sandbox bypass in Vim allows arbitrary OS command execution when a user opens a crafted file. The `complete`, `guitabtooltip` and `printheader` options are missing the `P_MLE` flag, allowing a modeline to be executed. Additionally, the `mapset()` function lacks a `check_secure()` call, allowing it to be abused from sandboxed expressions. Commit 9.2.0276 fixes the issue.","modified":"2026-04-16T11:05:36.673107Z","published":"2026-04-06T16:16:00Z","related":["USN-8171-1"],"upstream":["CVE-2026-34982"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2026-34982"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2026-34982"},{"type":"REPORT","url":"https://github.com/vim/vim/security/advisories/GHSA-8h6p-m6gr-mpw9"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-8171-1"}],"affected":[{"package":{"name":"vim","ecosystem":"Ubuntu:Pro:20.04:LTS","purl":"pkg:deb/ubuntu/vim@2:8.1.2269-1ubuntu5.32+esm3?arch=source&distro=esm-infra/focal"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2:8.1.2269-1ubuntu5.32+esm3"}]}],"versions":["2:8.1.0875-5ubuntu2","2:8.1.0875-5ubuntu3","2:8.1.0875-5ubuntu4","2:8.1.2269-1ubuntu1","2:8.1.2269-1ubuntu4","2:8.1.2269-1ubuntu5","2:8.1.2269-1ubuntu5.3","2:8.1.2269-1ubuntu5.4","2:8.1.2269-1ubuntu5.6","2:8.1.2269-1ubuntu5.7","2:8.1.2269-1ubuntu5.8","2:8.1.2269-1ubuntu5.9","2:8.1.2269-1ubuntu5.11","2:8.1.2269-1ubuntu5.12","2:8.1.2269-1ubuntu5.13","2:8.1.2269-1ubuntu5.14","2:8.1.2269-1ubuntu5.15","2:8.1.2269-1ubuntu5.16","2:8.1.2269-1ubuntu5.17","2:8.1.2269-1ubuntu5.18","2:8.1.2269-1ubuntu5.20","2:8.1.2269-1ubuntu5.21","2:8.1.2269-1ubuntu5.22","2:8.1.2269-1ubuntu5.23","2:8.1.2269-1ubuntu5.24","2:8.1.2269-1ubuntu5.25","2:8.1.2269-1ubuntu5.26","2:8.1.2269-1ubuntu5.29","2:8.1.2269-1ubuntu5.30","2:8.1.2269-1ubuntu5.31","2:8.1.2269-1ubuntu5.32","2:8.1.2269-1ubuntu5.32+esm2"],"ecosystem_specific":{"binaries":[{"binary_name":"vim","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"vim-athena","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"vim-common","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"vim-gtk","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"vim-gtk3","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"vim-gui-common","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"vim-nox","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"vim-runtime","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"vim-tiny","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"},{"binary_name":"xxd","binary_version":"2:8.1.2269-1ubuntu5.32+esm3"}],"availability":"Available
