CVE-2017-6903 medium priority: Ubuntu including 2 source packages (ioquake3, openarena), 46 status rows across 23 suites (artful, bionic, cosmic, disco, eoan, focal, groovy, hirsute, impish, jammy, kinetic, lunar, mantic, noble, oracular, plucky, precise, questing, trusty, upstream, xenial, yakkety, zesty): not-affected 32, ignored 9, DNE 2, needed 1, needs-triage 1, released 1.
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.
