{"id":"UBUNTU-CVE-2019-13012","details":"The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.60.0 creates directories using g_file_make_directory_with_parents (kfsb-\u003edir, NULL, NULL) and files using g_file_replace_contents (kfsb-\u003efile, contents, length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL). Consequently, it does not properly restrict directory (and file) permissions. Instead, for directories, 0777 permissions are used; for files, default file permissions are used. This is similar to CVE-2019-12450.","modified":"2026-02-04T04:40:39.920963Z","published":"2019-06-28T00:00:00Z","related":["USN-4049-1","USN-4049-2","USN-4049-3","USN-4049-4"],"upstream":["CVE-2019-13012"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2019-13012"},{"type":"REPORT","url":"https://gitlab.gnome.org/GNOME/glib/merge_requests/450"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4049-1"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4049-2"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4049-3"},{"type":"ADVISORY","url":"https://ubuntu.com/security/notices/USN-4049-4"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2019-13012"}],"affected":[{"package":{"name":"glib2.0","ecosystem":"Ubuntu:Pro:14.04:LTS","purl":"pkg:deb/ubuntu/glib2.0@2.40.2-0ubuntu1.1+esm3?arch=source&distro=trusty/esm"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.40.2-0ubuntu1.1+esm3"}]}],"versions":["2.38.0-1ubuntu1","2.38.1-1","2.39.1-0ubuntu1","2.39.1-0ubuntu2","2.39.1-0ubuntu3","2.39.2-0ubuntu1","2.39.2-0ubuntu2","2.39.3-0ubuntu4","2.39.4-0ubuntu1","2.39.90-0ubuntu1","2.39.91-0ubuntu2","2.39.91-0ubuntu3","2.39.92-2","2.40.0-1","2.40.0-1ubuntu1","2.40.0-2","2.40.2-0ubuntu1","2.40.2-0ubuntu1.1","2.40.2-0ubuntu1.1+esm1","2.40.2-0ubuntu1.1+esm2"],"ecosystem_specific":{"availability":"Available with Ubuntu Pro (Infra-only): https://ubuntu.com/pro","binaries":[{"binary_name":"libglib2.0-0","binary_version":"2.40.2-0ubuntu1.1+esm3"},{"binary_name":"libglib2.0-0-refdbg","binary_version":"2.40.2-0ubuntu1.1+esm3"},{"binary_name":"libglib2.0-bin","binary_version":"2.40.2-0ubuntu1.1+esm3"},{"binary_name":"libglib2.0-data","binary_version":"2.40.2-0ubuntu1.1+esm3"},{"binary_name":"libglib2.0-dev","binary_version":"2.40.2-0ubuntu1.1+esm3"},{"binary_name":"libglib2.0-tests","binary_version":"2.40.2-0ubuntu1.1+esm3"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13012.json"}},{"package":{"name":"glib2.0","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/glib2.0@2.48.2-0ubuntu4.4?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.48.2-0ubuntu4.4"}]}],"versions":["2.46.1-1","2.46.1-2","2.47.1-1","2.47.3-3","2.47.4-1","2.47.5-1","2.47.6-1","2.48.0-1ubuntu3","2.48.0-1ubuntu4","2.48.1-1~ubuntu16.04.1","2.48.2-0ubuntu1","2.48.2-0ubuntu3","2.48.2-0ubuntu4","2.48.2-0ubuntu4.1","2.48.2-0ubuntu4.2","2.48.2-0ubuntu4.3"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libglib2.0-0","binary_version":"2.48.2-0ubuntu4.4"},{"binary_name":"libglib2.0-0-refdbg","binary_version":"2.48.2-0ubuntu4.4"},{"binary_name":"libglib2.0-bin","binary_version":"2.48.2-0ubuntu4.4"},{"binary_name":"libglib2.0-data","binary_version":"2.48.2-0ubuntu4.4"},{"binary_name":"libglib2.0-dev","binary_version":"2.48.2-0ubuntu4.4"},{"binary_name":"libglib2.0-tests","binary_version":"2.48.2-0ubuntu4.4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13012.json"}},{"package":{"name":"glib2.0","ecosystem":"Ubuntu:18.04:LTS","purl":"pkg:deb/ubuntu/glib2.0@2.56.4-0ubuntu0.18.04.4?arch=source&distro=bionic"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"},{"fixed":"2.56.4-0ubuntu0.18.04.4"}]}],"versions":["2.54.1-1ubuntu1","2.55.2-2ubuntu1","2.56.0-2ubuntu1","2.56.0-4ubuntu1","2.56.1-2ubuntu1","2.56.2-0ubuntu0.18.04.1","2.56.2-0ubuntu0.18.04.2","2.56.3-0ubuntu0.18.04.1","2.56.4-0ubuntu0.18.04.2","2.56.4-0ubuntu0.18.04.3"],"ecosystem_specific":{"availability":"No subscription required","binaries":[{"binary_name":"libglib2.0-0","binary_version":"2.56.4-0ubuntu0.18.04.4"},{"binary_name":"libglib2.0-bin","binary_version":"2.56.4-0ubuntu0.18.04.4"},{"binary_name":"libglib2.0-data","binary_version":"2.56.4-0ubuntu0.18.04.4"},{"binary_name":"libglib2.0-dev","binary_version":"2.56.4-0ubuntu0.18.04.4"},{"binary_name":"libglib2.0-dev-bin","binary_version":"2.56.4-0ubuntu0.18.04.4"},{"binary_name":"libglib2.0-tests","binary_version":"2.56.4-0ubuntu0.18.04.4"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2019/UBUNTU-CVE-2019-13012.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:H/A:N"},{"type":"Ubuntu","score":"medium"}]}
