A NULL pointer dereference in Busyboxβs 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) An attacker-controlled pointer free in Busyboxβs 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. (CVE-2021-42377) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the getvar_i function. (CVE-2021-42378) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the next_input_file function. (CVE-2021-42379) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the clrvar function. (CVE-2021-42380) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the hash_init function. (CVE-2021-42381) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the getvar_s function. (CVE-2021-42382) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the evaluate function. (CVE-2021-42383) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the handle_special function. (CVE-2021-42384) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the evaluate function. (CVE-2021-42385) A use-after-free in Busyboxβs awk applet leads to denial of service and possibly code execution when processing a crafted awk pattern in the nvalloc function. (CVE-2021-42386)
