Summary
busybox security update
Details

BusyBox combines tiny versions of many common UNIX utilities into a single small executable. It provides replacements for most of the utilities you usually find in GNU fileutils, shellutils, etc. It provides a fairly complete environment for any small or embedded system.

Security Fix(es):

A use-after-free in Busybox s awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the nvalloc function.(CVE-2021-42386)

A NULL pointer dereference in Busybox s hush applet leads to denial of service when processing a crafted shell command, due to missing validation after a x03 delimiter character. This may be used for DoS under very rare conditions of filtered command input.(CVE-2021-42376)
