CVE-2021-42386 2 Busybox, Fedoraproject 2 Busybox, Fedora 2023-12-10 6.5 MEDIUM 7.2 HIGH
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-2021-42376 3 Busybox, Fedoraproject, Netapp 19 Busybox, Fedora, Cloud Backup and 16 more 2023-12-10 1.9 LOW 5.5 MEDIUM
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-2021-42382 2 Busybox, Fedoraproject 2 Busybox, Fedora 2023-12-10 6.5 MEDIUM 7.2 HIGH
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 getvar_s function
CVE-2021-28831 3 Busybox, Debian, Fedoraproject 3 Busybox, Debian Linux, Fedora 2023-12-10 5.0 MEDIUM 7.5 HIGH
decompress_gunzip.c in BusyBox through 1.32.1 mishandles the error bit on the huft_build result pointer, with a resultant invalid free or segmentation fault, via malformed gzip data.
CVE-2019-5747 2 Busybox, Canonical 2 Busybox, Ubuntu Linux 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in BusyBox through 1.30.0. An out of bounds read in udhcp components (consumed by the DHCP client, server, and/or relay) might allow a remote attacker to leak sensitive information from the stack by sending a crafted DHCP message. This is related to assurance of a 4-byte length when decoding DHCP_SUBNET. NOTE: this issue exists because of an incomplete fix for CVE-2018-20679.
CVE-2017-3209 2 Busybox, Dbpower 3 Busybox, U818a, U818a Firmware 2023-12-10 4.8 MEDIUM 8.1 HIGH
The DBPOWER U818A WIFI quadcopter drone provides FTP access over its own local access point, and allows full file permissions to the anonymous user. The DBPower U818A WIFI quadcopter drone runs an FTP server that by default allows anonymous access without a password, and provides full filesystem read/write permissions to the anonymous user. A remote user within range of the open access point on the drone may utilize the anonymous user of the FTP server to read arbitrary files, such as images and video recorded by the device, or to replace system files such as /etc/shadow to gain further access to the device. Furthermore, the DBPOWER U818A WIFI quadcopter drone uses BusyBox 1.20.2, which was released in 2012, and may be vulnerable to other known BusyBox vulnerabilities.
CVE-2018-20679 2 Busybox, Canonical 2 Busybox, Ubuntu Linux 2023-12-10 5.0 MEDIUM 7.5 HIGH
An issue was discovered in BusyBox before 1.30.0. 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.
CVE-2015-9261 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2023-12-10 4.3 MEDIUM 5.5 MEDIUM
huft_build in archival/libarchive/decompress_gunzip.c in BusyBox before 1.27.2 misuses a pointer, causing segfaults and an application crash during an unzip operation on a specially crafted ZIP file.
CVE-2018-1000500 1 Busybox 1 Busybox 2023-12-10 6.8 MEDIUM 8.1 HIGH
Busybox contains a Missing SSL certificate validation vulnerability in The "busybox wget" applet that can result in arbitrary code execution. This attack appear to be exploitable via Simply download any file over HTTPS using "busybox wget https://compromised-domain.com/important-file".
CVE-2018-1000517 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2023-12-10 7.5 HIGH 9.8 CRITICAL
BusyBox project BusyBox wget version prior to commit 8e2174e9bd836e53c8b9c6e00d1bc6e2a718686e contains a Buffer Overflow vulnerability in Busybox wget that can result in heap buffer overflow. This attack appear to be exploitable via network connectivity. This vulnerability appears to have been fixed in after commit 8e2174e9bd836e53c8b9c6e00d1bc6e2a718686e.
CVE-2017-15874 1 Busybox 1 Busybox 2023-12-10 4.3 MEDIUM 5.5 MEDIUM
archival/libarchive/decompress_unlzma.c in BusyBox 1.27.2 has an Integer Underflow that leads to a read access violation.
CVE-2017-16544 5 Busybox, Canonical, Debian and 2 more 8 Busybox, Ubuntu Linux, Debian Linux and 5 more 2023-12-10 6.5 MEDIUM 8.8 HIGH
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.
CVE-2011-5325 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2023-12-10 5.0 MEDIUM 7.5 HIGH

CVE-2016-6301 1 Busybox 1 Busybox 2023-12-10 7.8 HIGH 7.5 HIGH
The recv_and_process_client_pkt function in networking/ntpd.c in busybox allows remote attackers to cause a denial of service (CPU and bandwidth consumption) via a forged NTP packet, which triggers a communication loop.
CVE-2016-2148 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2023-12-10 7.5 HIGH 9.8 CRITICAL
Heap-based buffer overflow in the DHCP client (udhcpc) in BusyBox before 1.25.0 allows remote attackers to have unspecified impact via vectors involving OPTION_6RD parsing.

The add_probe function in modutils/modprobe.c in BusyBox before 1.23.0 allows local users to bypass intended restrictions on loading kernel modules via a / (slash) character in a module name, as demonstrated by an "ifconfig /usbserial up" command or a "mount -t /snd_pcm none /" command.
CVE-2016-2147 3 Busybox, Canonical, Debian 3 Busybox, Ubuntu Linux, Debian Linux 2023-12-10 5.0 MEDIUM 7.5 HIGH
Integer overflow in the DHCP client (udhcpc) in BusyBox before 1.25.0 allows remote attackers to cause a denial of service (crash) via a malformed RFC1035-encoded domain name, which triggers an out-of-bounds heap write.
CVE-2013-1813 3 Busybox, Redhat, T-mobile 3 Busybox, Enterprise Linux, Tm-ac1900 2023-12-10 7.2 HIGH N/A
