Descriptions

The kernel in NetBSD, probably 5.0.1 and earlier, on x86 platforms does not properly handle a pre-commit failure of the iret instruction, which might allow local users to gain privileges via vectors related to a tempEIP pseudocode variable that is outside of the code-segment limits.

El kernel en NetBSD, posiblemente 5.0.1 y anteriores, en plataformas x86 no gestiona adecuadamente el fallo de preasignación de la instrucción "iret", lo que permitiría a usuarios locales conseguir privilegios a través de vectores relacionados con la variable de pseudocódigo tempEIP que esta fuera de los limites de segmento de código.
