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.

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 •

An issue was discovered in the Linux kernel before 5.14.8. A use-after-free in selinux_ptrace_traceme (aka the SELinux handler for PTRACE_TRACEME) could be used by local attackers to cause memory corruption and escalate privileges, aka CID-a3727a8bac0a. This occurs because of an attempt to access the subjective credentials of another task. Se ha detectado un problema en el kernel de Linux versiones anteriores a 5.14.8. Un uso de memoria previamente liberada en la función selinux_ptrace_traceme (también conocido como el manejador de SELinux para PTRACE_TRACEME) podría ser usado por atacantes locales para causar una corrupción de memoria y escalar privilegios, también se conoce como CID-a3727a8bac0a. • https://bugs.chromium.org/p/project-zero/issues/detail?id=2229 https://cdn.kernel.org/pub/linux/kernel/v5.x/ChangeLog-5.14.8 https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a3727a8bac0a9e77c70820655fd8715523ba3db7 https://security.netapp.com/advisory/ntap-20211125-0001 • CWE-416: Use After Free •
