Descriptions
The __driver_rfc4106_decrypt function in arch/x86/crypto/aesni-intel_glue.c in the Linux kernel before 3.19.3 does not properly determine the memory locations used for encrypted data, which allows context-dependent attackers to cause a denial of service (buffer overflow and system crash) or possibly execute arbitrary code by triggering a crypto API call, as demonstrated by use of a libkcapi test program with an AF_ALG(aead) socket.
La función __driver_rfc4106_decrypt en arch/x86/crypto/aesni-intel_glue.c en el kernel de Linux anterior a 3.19.3 no determina correctamente las localizaciones de memoria utilizadas para datos cifrados, Lo que permite a atacantes dependientes de contexto causar una denegación de servicio (desbordamiento de buffer y caída de sistema) o posiblemente ejecutar código arbitrario mediante la provocación de una llamada de API Crypto, tal y como fue demostrado por el uso de un programa de pruebas de libkcapi con un socket AF_ALG(aead).
A buffer overflow flaw was found in the way the Linux kernel's Intel AES-NI instructions optimized version of the RFC4106 GCM mode decryption functionality handled fragmented packets. A remote attacker could use this flaw to crash, or potentially escalate their privileges on, a system over a connection with an active AES-GCM mode IPSec security association.
