Description

QNX Neutrino RTOS contains a flaw that may allow a local user to gain elevated privileges. The issue is due to the /etc/rc.d/rc.local file installing with world writeable permissions. This allows any user to add arbitrary commands that will be executed with root privileges upon the next system startup.

Solution

Currently, there are no known upgrades or patches to correct this issue. It is possible to correct the flaw by implementing the following workaround: change the permission of /etc/rc.d/rc.local to something more restrictive such as 644
