Descriptions

The IA32 system call emulation functionality in Linux kernel 2.4.x and 2.6.x before 2.6.22.7, when running on the x86_64 architecture, does not zero extend the eax register after the 32bit entry path to ptrace is used, which might allow local users to gain privileges by triggering an out-of-bounds access to the system call table using the %RAX register.

La funcionalidad de emulación de llamada del sistema IA32 en Linux kernel 2.4.x y 2.6.x versiones anteriores a 2.6.22.7, cuando se ejecuta en arquitecturas x86_64, no extiende a cero el registro eax después de ser usada una ruta de entrada 32bit en ptrace, lo cual podría permitir a usuarios locales, obtener privilegios al disparar un acceso fuera de límites en la tabla de llamadas del sistema utilizando el registro %RAX.
