An incorrect handling of a special element in Busybox ash leads to denial of service when processing malformed command line arguments
BusyBox [1.33.0, 1.33.1], fixed in 1.34.0
The BusyBox toolkit implements a large number of Linux tools in a single executable and can even replace the Linux init system. Its small size and flexibility make it popular in embedded devices.
An incorrect handling of a special element in ash leads to denial of service when processing a crafted shell command, due to the shell mistaking specific characters for reserved characters. This may be used for DoS under rare conditions of filtered command input.
An attacker that controls ash command line arguments can trigger this issue.
