Prevent processes from reading userspace

0

I was trying to read and write values from a process with a program (ceserver, part of the CheatEngine project) which both ran in user-space (without root). I didn't expect it to work, however unfortunately it did, I could even manipulate the memory (e.g manipulating the text inside the editor etc.). I wanted to ask if that's a security leak and if, how fatal it is and how to prevent that.

Sounds like a good question for the linux site – Griffin – 2015-06-11T14:39:47.253

You mean it doesn't have anything to do with user configuration? Well, you're probably right, I'm removing it from here. ty for the .suggestion – The19thFighter – 2015-06-11T14:40:52.357

No, I mean they are to know how it is going to interact. I'm not sure what program you're talking about or if you built it yourself. If you built it yourself they'll likely be more helpful. – Griffin – 2015-06-11T14:42:23.200

You may get an answer here but you know that you're going to be working on Linux and they specialize in Linux – Griffin – 2015-06-11T14:43:23.310

No, but it's not this much used, I'm using ceserver, which is part of the CheatEngine project. But it uses nothing special so even other programms like scanmem should be able to do that. – The19thFighter – 2015-06-11T14:43:24.443

I don't know never used it but that's definitely information you should include in your question – Griffin – 2015-06-11T14:44:39.777

ok, thank you I'm going to reopen this at the Linux site, including your suggestion. – The19thFighter – 2015-06-11T14:46:09.833

You can wait a bit. Depending on how mission critical it is. Maybe a few hours. Giving SU guys a chance to answer :p it also prevents unnecessary cross site questions – Griffin – 2015-06-11T14:48:45.653

Don't worry. I'm just waiting to copy that. k, I'll just wait first, and meanwhile, edit it. – The19thFighter – 2015-06-11T14:48:54.963

@The19thFighter Just as a followup did you ever get an answer? – Griffin – 2015-06-24T19:31:52.450

I didn't post it somewhere else. – The19thFighter – 2015-06-26T05:17:40.870
