Descriptions

An issue was discovered in secdrv.sys as shipped in Microsoft Windows Vista, Windows 7, Windows 8, and Windows 8.1 before KB3086255, and as shipped in Macrovision SafeDisc. Two carefully timed calls to IOCTL 0xCA002813 can cause a race condition that leads to a use-after-free. When exploited, an unprivileged attacker can run arbitrary code in the kernel.

Se ha descubierto un problema en secdrv.sys, tal y como se distribuye en Microsoft Windows Vista, Windows 7, Windows 8 y Windows 8.1 en versiones anteriores a la KB3086255 y tal y como se distribuye en Macrovision SafeDisc. Dos llamadas cuidadosamente calculadas a IOCTL 0xCA002813 pueden provocar una condición de carrera que conduce a un uso de memoria previamente liberada. Al explotarse este problema, un atacante no privilegiado puede ejecutar código arbitrario en el kernel.
