Descriptions

Linux drivers/char/lp.c Out-of-Bounds Write. Due to a missing bounds check, and the fact that parport_ptr integer is static, a 'secure boot' kernel command line adversary (can happen due to bootloader vulns, e.g. Google Nexus 6's CVE-2016-10277, where due to a vulnerability the adversary has partial control over the command line) can overflow the parport_nr array in the following code, by appending many (>LP_NO) 'lp=none' arguments to the command line.

Una escritura fuera de límites en el archivo drivers/char/lp.c de Linux, Debido a la falta de comprobación de límites, y al hecho de que el entero parport_ptr es estático, un adversario de línea de comando del kernel "secure boot" (puede ocurrir debido a vulnerabilidades del cargador de arranque, por ejemplo, CVE-2016-10277 de Google Nexus 6, donde debido a una vulnerabilidad el adversario tiene control parcial sobre la línea de comando) puede desbordar la matriz parport_nr en el siguiente código, mediante la incorporación muchos argumentos (mayor que LP_NO) 'lp=none' hacia la línea de comando.
