Assigned:2021-11-09
Published:2021-11-09
Updated:2022-03-31
Summary:An attacker-controlled pointer free in Busybox's hush applet leads to denial of service and possible code execution when processing a crafted shell command, due to the shell mishandling the &&& string. This may be used for remote code execution under rare conditions of filtered command input.
