CVE-2026-26157 [HIGH] CVE-2026-26157: busybox - A flaw was found in BusyBox. Incomplete path sanitization in its archive extract... A flaw was found in BusyBox. Incomplete path sanitization in its archive extraction utilities allows an attacker to craft malicious archives that when extracted, and under specific conditions, may write to files outside the intended directory. This can lead to arbitrary file overwrite, potentially enabling code execution through the modification of sensitive system

CVE-2021-42377 [CRITICAL] CVE-2021-42377: busybox - An attacker-controlled pointer free in Busybox's hush applet leads to denial of ... 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. Scope: local bookworm: resolved (fixed in 1:1.35.0-1) bullseye: open f

CVE-2017-16544 [HIGH] CVE-2017-16544: busybox - In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab... In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature of the shell, used to get a list of filenames in a directory, does not sanitize filenames and results in executing any escape sequence in the terminal. This could potentially result in code execution, arbitrary file writes, or other attacks. Scope: local bookworm: r

An out of bounds read in udhcp components (consumed by the DHCP server, client, and relay) allows a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to verification in udhcp_get_option() in networking/udhcp/common.c that 4-byte options are indeed 4 bytes.
