Descriptions

The crypto API in the Linux kernel through 3.9-rc8 does not initialize certain length variables, which allows local users to obtain sensitive information from kernel stack memory via a crafted recvmsg or recvfrom system call, related to the hash_recvmsg function in crypto/algif_hash.c and the skcipher_recvmsg function in crypto/algif_skcipher.c.

La API crypto en el kernel de Linux hasta v3.9-rc8 no inicializa cierta longitud de variables, permitiendo a usuarios locales obtener información sensible desde la pila del kernel mediante una syscall recvmsg o recvfrom especialmente diseñada, relacionado con la función hash_recvmsg en crypto/algif_hash.c y la función skcipher_recvmsg en crypto/algif_skcipher.c.
