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_i function
CVE-2021-42374 3 Busybox, Fedoraproject, Netapp 19 Busybox, Fedora, Cloud Backup and 16 more 2025-11-03 3.3 LOW 5.3 MEDIUM
An out-of-bounds heap read in Busybox's unlzma applet leads to information leak and denial of service when crafted LZMA-compressed input is decompressed. This can be triggered by any applet/format that
CVE-2022-28391 1 Busybox 1 Busybox 2025-06-09 6.8 MEDIUM 8.8 HIGH
BusyBox through 1.35.0 allows remote attackers to execute arbitrary code if netstat is used to print a DNS PTR record's value to a VT compatible terminal. Alternatively, the attacker could choose to change the terminal's colors.
CVE-2019-5747 2 Busybox, Canonical 2 Busybox, Ubuntu Linux 2025-06-09 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-2018-20679 2 Busybox, Canonical 2 Busybox, Ubuntu Linux 2025-06-09 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.
