{"id":"UBUNTU-CVE-2017-6903","details":"In ioquake3 before 2017-03-14, the auto-downloading feature has insufficient content restrictions. This also affects Quake III Arena, OpenArena, OpenJK, iortcw, and other id Tech 3 (aka Quake 3 engine) forks. A malicious auto-downloaded file can trigger loading of crafted auto-downloaded files as native code DLLs. A malicious auto-downloaded file can contain configuration defaults that override the user's. Executable bytecode in a malicious auto-downloaded file can set configuration variables to values that will result in unwanted native code DLLs being loaded, resulting in sandbox escape.","modified":"2025-10-24T04:46:12Z","published":"2017-03-14T22:59:00Z","upstream":["CVE-2017-6903"],"references":[{"type":"REPORT","url":"https://ubuntu.com/security/CVE-2017-6903"},{"type":"REPORT","url":"https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=857699"},{"type":"REPORT","url":"https://github.com/ioquake/ioq3/commit/376267d534476a875d8b9228149c4ee18b74a4fd"},{"type":"REPORT","url":"https://github.com/ioquake/ioq3/commit/b173ac05993f634a42be3d3535e1b158de0c3372"},{"type":"REPORT","url":"https://github.com/ioquake/ioq3/commit/f61fe5f6a0419ef4a88d46a128052f2e8352e85d"},{"type":"REPORT","url":"https://github.com/iortcw/iortcw/commit/11a83410153756ae350a82ed41b08d128ff7f998"},{"type":"REPORT","url":"https://github.com/iortcw/iortcw/commit/b248763e4878ef12d5835ece6600be8334f67da1"},{"type":"REPORT","url":"https://github.com/iortcw/iortcw/commit/b6ff2bcb1e4e6976d61e316175c6d7c99860fe20"},{"type":"REPORT","url":"https://github.com/JACoders/OpenJK/commit/8956a35e7b91c4a0dd1fa6db1d28c7f0efbab2d7"},{"type":"REPORT","url":"https://ioquake3.org/2017/03/13/important-security-update-please-update-ioquake3-immediately/"},{"type":"REPORT","url":"https://www.cve.org/CVERecord?id=CVE-2017-6903"}],"affected":[{"package":{"name":"ioquake3","ecosystem":"Ubuntu:16.04:LTS","purl":"pkg:deb/ubuntu/ioquake3@1.36+u20160122+dfsg1-1?arch=source&distro=xenial"},"ranges":[{"type":"ECOSYSTEM","events":[{"introduced":"0"}]}],"versions":["1.36+u20150710+dfsg1-1","1.36+u20150926+dfsg1-1","1.36+u20151017+dfsg1-1","1.36+u20160122+dfsg1-1"],"ecosystem_specific":{"binaries":[{"binary_version":"1.36+u20160122+dfsg1-1","binary_name":"ioquake3"},{"binary_version":"1.36+u20160122+dfsg1-1","binary_name":"ioquake3-server"}]},"database_specific":{"source":"https://github.com/canonical/ubuntu-security-notices/blob/main/osv/cve/2017/UBUNTU-CVE-2017-6903.json"}}],"schema_version":"1.7.3","severity":[{"type":"CVSS_V3","score":"CVSS:3.0/AV:L/AC:L/PR:N/UI:R/S:U/C:H/I:H/A:H"},{"type":"Ubuntu","score":"medium"}]}
