🦑Google engineer: 70% of Chrome security vulnerabilities are memory security issues, and Rust has become an alternative language
recently from our tweets @ UndercodeNews :


1) Recently, a Google engineer analyzed 912 security bugs fixed in the Chrome stable branch since 2015. And found that among all the security vulnerabilities marked as "high" or "serious", about 70% are memory management and security issues.

2) Half of these are use-after-free vulnerabilities. This security issue is caused by the wrong management of memory pointers (addresses), opening the door for attackers to attack Chrome's internal components.

🦑 This data happens to be the same as Microsoft ’s previous research results : The Microsoft Security Response Center (MSRC) classified all reported Microsoft security vulnerabilities since 2004, and about 70% of all Microsoft ’s annual patches are for memory security vulnerabilities. Fix.

1) The Microsoft Security Response Center once explained that this is because most of their products are written in C and C ++, and these two programming languages ​​belong to the category of "memory-unsafe". A vulnerability in the developer code that manages memory execution can lead to a series of memory security errors.

2)) Google also faces a similar situation. Only from March 2019 to the present, out of 130 Chrome vulnerabilities rated "serious", 125 are related to memory corruption, which shows that memory management is still a big problem.

3) To this end, Google engineers must follow " The Rule of 2 " ( The Rule of 2 ). That is, whenever an engineer writes a new Chrome feature, its code must not break the following two or more conditions:

>This code handles untrusted input
Code runs without sandbox
Code is written in an unsafe programming language (C / C ++)

1)So far, Google has been trying to use the sandbox method in Chrome. They isolate dozens of processes into their own sandboxes, and recently introduced the "site isolation" feature, which puts the resources of each site into their own sandbox processes. But Google engineers said that considering performance issues, their method of using sandboxed Chrome components has reached the maximum benefit, and they must now seek new methods.

2) Therefore, Google plans to research and develop custom C ++ libraries for use with Chrome ’s codebase, which can better protect memory-related errors.

3) At the same time, Google is also exploring the MiraclePtr project, which aims to turn "use-after-free bugs into unsafe crashes with acceptable performance, memory, binary size, and minimal stability impact."

4) Finally, it is worth noting that Google has indicated that it plans to use "safe" language to explore when possible. Candidates include Rust, Swift, JavaScript, Kotlin, and Java.

🦑2020 Min Linux Steam Requirements-from git sources :

team for Linux requires the following:

1 GHz Pentium 4 or AMD Opteron with:

1) x86-64 (AMD64) instruction set

2) CMPXCHG16B instruction support (cx16 in /proc/cpuinfo flags)

3) SSE3 instruction support (pni in /proc/cpuinfo flags)

4) 512 megabytes of RAM and 5 gigabytes of hard drive space, or better

5) Internet connection (Cable/DSL speeds recommended)

6) Latest Ubuntu LTS, fully updated

7) 64-bit (x86-64, AMD64) Linux kernel

8) 64-bit (x86-64, AMD64) and 32-bit (i386, IA32) graphics drivers and glibc

9) Latest graphics driver

10) NVidia driver support - For recent cards (e.g. series 8), you will need to install 310.x. For older cards, driver 304.x supports the NVidia 6 and 7 GPU series. To access these drivers, first update your cache and then install the specific driver you need from the list in Additional Drivers.

11) AMD driver support - For recent cards (e.g. series 5 and above), we recommend installing the 12.11 driver. For older cards, Catalyst 13.1 Legacy supports the HD 2400 Pro card and is the latest for the 2 and 4 GPU series.

12) Intel HD 3000/4000 driver support - you will need to use the latest Mesa drivers, Mesa 9 or later.

🦑 Modify the configuration file

After entering the project interface, click "Help"-> "Edit Custom VM Options…" in the top menu bar of Idea. If you are prompted to create a file, click "Yes".

🦑 At the end of the opened vmoptions edit window,




> add:-javaagent: idea\jetbrains-agent.jar

🦑 Please carefully check whether the patch path is correct. If it is wrong, the Idea will not open. At this time, you can delete the Idea folder in the user configuration directory:

1) windwos: C: \ Users \ user name \

2) macos: ~ / Library / Preferences /

3) ubuntu: ~

> After modifying the configuration file, restart Idea

4) Enter the activation code

After restarting Idea, click "Help"-> "Register…" in the menu bar, there are two activation methods:

> Choose the last license server activation method, fill in the address: http://jetbrains-license-server(it should be automatically filled in), or click the button: "Discover Server" to automatically fill in the address and complete the activation

5) If the server activation method cannot be activated, you can also select Activation code to activate, copy the activation code below :


pastebin.com/r8A6W7am


6) View the validity period

When your activation is complete, there will be a small registration prompt box in the lower right corner of Idea. The general content is: You copy is Licensed to XXX, it will tell you: Brother, you have activated successfully, and the source of the activation code is : XXX.

7) To check the validity period, click: Help-> About Here you can see the version number, license source, validity period, and some environments of your Idea

There is no time limit for server activation, which is permanently valid
