EMERGENCY UPDATE

EMERGENCY UPDATE

Features

• Fixed the bugs of the judger (forgetting to remove temp output after executing a program)
• A bug still exists: The input data should be in the format of mac/unix/linux, if it contains '\r', some submissions will have problems with their scores. The solution to this bug has been found but it'll be fixed in the next version.
• Note: v0.1.* CANNOT BE PUT INTO A PRODUCTION ENVIRONMENT because of the bugs and the instability!!!!

Existing Bugs

You can run a program like this:

#include<cstdlib>
int main() {
    system("reboot");
    return 0;
}

The program will reboot the machine if you run node in the root mode.

Solution:

• Use chroot to build a sandbox to avoid hacking like this
• Use restricted Memory Usage Limitations to avoid those who submit a judger-hacking program. (by ulimit -v)

The Database authentication model (or config) is not used, so if you're building a judging-server using this build(or earlier build), please be careful with the setting of MONGODB SERVER.

Finally

Thanks to the bug reporter @LXLWDGY
