It's an obvious vulnerability, because a local attacker can make setuid() fail by setting a resource limit of 0 for RLIMIT_NPROC with setrlimit().Does that have any security implications though? I've not looked at the app. If it's a security problem, I'll give it a CVE id.
I didn't really look either. Because of this, everything will run as root while it shouldn't, but an attacker might need a second bug to elevate privileges. I would still consider it a security problem. Julien
