CVE-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.

CVE-2017-17805 – kernel: Salsa20 encryption algorithm does not correctly handle zero-length inputs allowing local attackers to cause denial-of-service
https://notcve.org/view.php?id=CVE-2017-17805
The Salsa20 encryption algorithm in the Linux kernel before 4.14.8 does not correctly handle zero-length inputs, allowing a local attacker able to use the AF_ALG-based skcipher interface (CONFIG_CRYPTO_USER_API_SKCIPHER) to cause a denial of service (uninitialized-memory free and kernel crash) or have unspecified other impact by executing a crafted sequence of system calls that use the blkcipher_walk API. Both the generic implementation (crypto/salsa20_generic.c) and x86 implementation (arch/x86/crypto/salsa20_glue.c) of Salsa20 were vulnerable. El algoritmo de cifrado Salsa20 en el kernel de Linux en versiones anteriores a la 4.14.8 no maneja correctamente las entradas de longitud cero, lo que permite a un atacante local capaz de utilizar la interfaz skcipher basada en AF_ALG (CONFIG_CRYPTO_USER_API_SKCIPHER) provocar una denegación de servicio (liberación de memoria no inicializada y fallo del kernel) o provocar otro impacto no especificado ejecutando una secuencia manipulada de llamadas al sistema que utilizan la API blkcipher_walk. Tanto la implementación genérica (crypto/salsa20_generic.c) como la implementación x86 (arch/x86/crypto/salsa20_glue.c) de Salsa20 eran vulnerables. The Salsa20 encryption algorithm in the Linux kernel, before 4.14.8, does not correctly handle zero-length inputs. • http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=ecaaab5649781c5a0effdaf298a925063020500e http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00006.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00007.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00008.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00014.html http://lists.opensuse.org/opensuse-security-announce/2018-01/msg00016.html http://www.securityfocus. • CWE-20: Improper Input Validation •
