CVE-2010-4656

La función iowarrior_write en drivers/usb/misc/iowarrior.c en el kernel Linux anterior a v2.6.37 no asigna memoria adecuadamente, lo que permite a usuarios locales desencadenar un desbordamiento de búfer basado en memoria dinámica, y en consecuencia provocar una denegación de servicio o obtener privilegios a través de un informe largo.

Dan Rosenberg discovered that IRDA did not correctly check the size of buffers. On non-x86 systems, a local attacker could exploit this to read kernel heap memory, leading to a loss of privacy. Dan Rosenburg discovered that the CAN subsystem leaked kernel addresses into the /proc filesystem. A local attacker could use this to increase the chances of a successful memory corruption exploit. Kees Cook discovered that the IOWarrior USB device driver did not correctly check certain size fields. A local attacker with physical access could plug in a specially crafted USB device to crash the system or potentially gain root privileges. Various other issues were also addressed.
