CVE-2016-6301
HighSummary
The recv_and_process_client_pkt function in networking/ntpd.c in busybox allows remote attackers to cause a denial of service via a forged NTP packet, triggering a communication loop.
Risk Assessment
Attackers can exploit this vulnerability to exhaust CPU and bandwidth resources, potentially disrupting service operations.
Recommendation
It is recommended to update busybox to the latest version to mitigate this vulnerability and to monitor NTP traffic for suspicious packets.
Other vulnerabilities in busybox
See all- CVE-2017-16544High
In the add_match function in libbb/lineedit.c in BusyBox through 1.27.2, the tab autocomplete feature does not sanitize filenames, potentially leading to executing any escape sequences in the terminal.
- CVE-2011-5325High
Directory traversal vulnerability in the BusyBox implementation of tar before version 1.22.0 v5 allows remote attackers to point to files outside the current working directory via a symlink.
- CVE-2016-2147High
Integer overflow in the DHCP client (udhcpc) in BusyBox before version 1.25.0 allows remote attackers to cause a denial of service (crash) via a malformed RFC1035-encoded domain name, leading to an out-of-bounds heap write.
- CVE-2022-48174Critical
A stack overflow vulnerability exists in ash.c:6030 in busybox before version 1.35. In the Internet of Vehicles environment, it can be exploited from command execution to arbitrary code execution.
- CVE-2026-76014Low
A vulnerability was found in BusyBox up to version 1.30.1 in the file networking/wget.c, in the FEATURE_WGET_TIMEOUT Handler component. Manipulation of the -T argument leads to a null pointer dereference. Local access is required. The exploit has been disclosed, and a patch is available (commit 83a40bf7a93c8ac093d33ab452222dd5b9eb57ff).
- CVE-2026-38755Low
A heap overflow in the evalcommand() function (shell/ash.c) of BusyBox v1.38.0 allows attackers to cause a Denial of Service (DoS) via supplying a crafted input.
- CVE-2026-38754Medium
Heap overflow in the ifsbreakup() function (shell/ash.c) of Busybox v1.38.0. An attacker can cause a Denial of Service (DoS) by supplying crafted input.
- CVE-2026-38752Low
A stack overflow vulnerability exists in the evaluate() function (editors/awk.c) of BusyBox commit 371fe9. Attackers can cause a Denial of Service (DoS) by supplying a crafted AWK script.
- CVE-2026-38753Medium
A use-after-free vulnerability in the awk_sub() function (editors/awk.c) of BusyBox v1.38.0 allows attackers to cause a Denial of Service (DoS) by supplying a crafted AWK script.
- CVE-2026-29004High
BusyBox before commit 42202bf has a heap buffer overflow vulnerability in the DHCPv6 client (udhcpc6) DNS_SERVERS option handler. A network-adjacent attacker can send a crafted DHCPv6 response with a malformed D6_OPT_DNS_SERVERS option to trigger memory corruption.
