calling qnx_vc_attach on idle process crashes qnx

QNX USERS QNX2 and QNX4

Hi,

It might be me misunderstanding something but, atleast in 4.23 , calling qnx_vc_attach on the idle process (usually a low pid , 8 in my case ) causes the whole QNX kernel to hang. This could be used by local users for Denial of service… anyone know if this still happens on 4.25?

Frankly, security is not a big concern of QSS. The argument I heard was you only use QNX in a secured environment. You should trust your local users, right? :slight_smile:
