A missing authorization check in the fscrypt_process_policy function in fs/crypto/policy.c in the ext4 and f2fs filesystem encryption support in the Linux kernel before 4.7.4 allows a user to assign an encryption policy to a directory owned by a different user, potentially creating a denial of service. Una comprobación de autorización que falta en la función fscrypt_process_policy en fs/crypto/policy.c en el soporte de cifrado del sistema de archivos ext4 y f2fs en el kernel de Linux en versiones anteriores a 4.7.4 permite a un usuario asignar una política de cifrado a un directorio propiedad de un usuario diferente, potencialmente creando una denegación de servicio. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=163ae1c6ad6299b19e22b4a35d5ab24a89791a98 http://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.7.4 http://www.securityfocus.com/bid/97404 https://github.com/torvalds/linux/commit/163ae1c6ad6299b19e22b4a35d5ab24a89791a98 • CWE-264: Permissions, Privileges, and Access Controls •

The eCryptfs subsystem in the Linux kernel before 3.18 allows local users to gain privileges via a large filesystem stack that includes an overlayfs layer, related to fs/ecryptfs/main.c and fs/overlayfs/super.c. El subsistema eCryptfs en el kernel de Linux en versiones anteriores a 3.18 permite a los usuarios locales obtener privilegios a través de una pila de archivos grande que incluye una capa de superposición, relacionada con fs/ecryptfs/main.c y fs/overlayfs/super.c. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=69c433ed2ecd2d3264efd7afec4439524b319121 http://source.android.com/security/bulletin/2017-04-01.html http://www.securityfocus.com/bid/97354 http://www.securitytracker.com/id/1038201 https://github.com/torvalds/linux/commit/69c433ed2ecd2d3264efd7afec4439524b319121 • CWE-264: Permissions, Privileges, and Access Controls •

CVSS: 7.8EPSS: 0%CPEs: 22EXPL: 0CVE-2017-17806 – kernel: HMAC implementation does not validate that the underlying cryptographic hash algorithm is unkeyed allowing local attackers to cause denial-of-service
https://notcve.org/view.php?id=CVE-2017-17806
The HMAC implementation (crypto/hmac.c) in the Linux kernel before 4.14.8 does not validate that the underlying cryptographic hash algorithm is unkeyed, allowing a local attacker able to use the AF_ALG-based hash interface (CONFIG_CRYPTO_USER_API_HASH) and the SHA-3 hash algorithm (CONFIG_CRYPTO_SHA3) to cause a kernel stack buffer overflow by executing a crafted sequence of system calls that encounter a missing SHA-3 initialization. La implementación HMAC (crypto/hmac.c) en el kernel de Linux en versiones anteriores a la 4.14.8 no valida que el algoritmo de hash criptográfico subyacente no tenga clave, lo que permite que un atacante local capaz de utilizar la interfaz hash basada en AF_ALG (CONFIG_CRYPTO_USER_API_HASH) y el algoritmo hash basado en SHA-3 (CONFIG_CRYPTO_SHA3) provoque un desbordamiento de búfer de pila de kernel ejecutando una secuencia manipulada de llamadas al sistema para encontrar una inicialización SHA-3 ausente.
