Upgrade Alpine:3.19 busybox to version 1.34.0-r0 or higher.
NVD Description
Note: Versions mentioned in the description apply only to the upstream busybox package and not the busybox package as distributed by Alpine.
See How to fix? for Alpine:3.19 relevant fixed versions and status.
An incorrect handling of a special element in Busybox's ash applet 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.
