      "value": "An issue was discovered in the Linux kernel through 4.17.3. An Integer Overflow in kernel/time/posix-timers.c in the POSIX timer code is caused by the way the overrun accounting works. Depending on interval and expiry time values, the overrun can be larger than INT_MAX, but the accounting is int based. This basically makes the accounting values, which are visible to user space via timer_getoverrun(2) and siginfo::si_overrun, random. For example, a local user can cause a denial of service (signed integer overflow) via crafted mmap, futex, timer_create, and timer_settime system calls."

      "value": "Se ha descubierto un problema en el kernel de Linux hasta la versi\u00f3n 4.17.3. Un desbordamiento de enteros en kernel/time/posix-timers.c en el c\u00f3digo temporizador POSIX es causado por la forma en que funciona la contabilidad de desbordamiento. Dependiendo de los valores del intervalo y del tiempo de expiraci\u00f3n, el desbordamiento puede ser mayor que INT_MAX, pero la contabilidad est\u00e1 basada en int. Esto b\u00e1sicamente hace que los valores contables, que son visibles para el espacio de usuario a trav\u00e9s de timer_getoverrun(2) y siginfo::si_overrun, sean aleatorios. Por ejemplo, un usuario local puede causar una denegaci\u00f3n de servicio (desbordamiento de enteros firmados) a trav\u00e9s de llamadas al sistema mmap, futex, timer_create y timer_settime manipuladas."
