CVE-2017-16544 is fixed in 6 products on 1 platform, first by busybox 1:1.27.2-1ubuntu4, released November 19, 2017. It is not reported as exploited. Patch Radar priority: Routine.
In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks.
