DESCRIPTION:
lms has reported a weakness in QNX RTOS, which potentially can be
exploited by malicious, local users to cause a DoS (Denial of
Service).
The weakness is caused due to the "dhcp.client" program having suid
root permissions. This can be exploited by malicious users to change
the assigned IP addresses of network interfaces, potentially causing
a DoS.
The weakness has been reported in version 4.25. Other versions may
also be affected.
SOLUTION:
Remove the suid bit from "dhcp.client".
