An incorrect handling of a special element in Busybox's ash applet leads to denial of service when processing a crafted shell command, due to the shell mistaking specific characters for reserved characters. This may be used for DoS under rare conditions of filtered command input. Un manejo incorrecto de un elemento especial en el applet ash de Busybox conlleva una denegación de servicio cuando es procesado un comando shell diseñado, debido a que el shell confunde caracteres específicos con caracteres reservados.

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. Una desreferencia de puntero NULL en el applet hush de Busybox conlleva a una denegación de servicio cuando es procesado un comando shell diseñado, debido a una falta de comprobación después de un carácter delimitador \x03.

https://notcve.org/view.php?id=CVE-2021-42377
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. Un puntero libre controlado por un atacante en el applet hush de Busybox conlleva a una denegación de servicio y una posible ejecución de código cuando es procesado un comando shell diseñado, debido a que el shell maneja inapropiadamente la cadena &&&.

CVSS: 9.8EPSS: 4%CPEs: 18EXPL: 3CVE-2021-43267 – kernel: Insufficient validation of user-supplied sizes for the MSG_CRYPTO message type
https://notcve.org/view.php?id=CVE-2021-43267
An issue was discovered in net/tipc/crypto.c in the Linux kernel before 5.14.16. The Transparent Inter-Process Communication (TIPC) functionality allows remote attackers to exploit insufficient validation of user-supplied sizes for the MSG_CRYPTO message type. Se ha detectado un problema en el archivo net/tipc/crypto.c en el kernel de Linux versiones anteriores a 5.14.16. La funcionalidad Transparent Inter-Process Communication (TIPC) permite a atacantes remotos explotar una comprobación insuficiente de los tamaños suministrados por el usuario para el tipo de mensaje MSG_CRYPTO A flaw was discovered in the cryptographic receive code in the Linux kernel's implementation of transparent interprocess communication. An attacker, with the ability to send TIPC messages to the target, can corrupt memory and escalate privileges on the target system. • https://github.com/zzhacked/CVE-2021-43267 https://github.com/DarkSprings/CVE-2021-43267-POC http://www.openwall.com/lists/oss-security/2022/02/10/1 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.14.16 https://github.com/torvalds/linux/commit/fa40d9734a57bcbfa79a280189799f76c88f7bb0 https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/CVWL7HZV5T5OEKJPO2D67RMFMKBBXGGB https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message&# • CWE-20: Improper Input Validation CWE-1284: Improper Validation of Specified Quantity in Input •
