Descriptions
The ecryptfs_write_metadata_to_contents function in the eCryptfs functionality in the Linux kernel 2.6.28 before 2.6.28.9 uses an incorrect size when writing kernel memory to an eCryptfs file header, which triggers an out-of-bounds read and allows local users to obtain portions of kernel memory.
La función ecryptfs_write_metadata_to_contents en la funcionalidad eCryptfs en el kernel Linux v2.6.28 anterior a v2.6.28.9 emplea un tamaño incorrecto cuando escribe de la memoria del kernel a la cabecera del archivo eCryptfs, lo que dispara una lectura fuera de rango y permite a usuarios locales obtener porciones d la memoria del kernel.
