The project DOSBox is a fantastic emulator for the MS-DOS operating system that we can install on Linux to be able to run classic video games and native programs from this old Microsoft system. Surely you already know it, with it you can resurrect a large amount of old software and it is very easy to use. In fact, we have already dedicated some articles in LxA explaining how it works, etc.
In the last times, the project seemed somewhat dead. But the truth is that it is not. It has been updated again with a bug that has been fixed. The truth is that it works well now, but it is not bad that it continues to be polished. You can visit the official website DOSBox to get more information about the project, documents and download the latest version of this emulator if you need it. The version is DOSBox 0.74 and the improvement has to do with security ...
DOSBox is still alive and the changes added are:
- Fixed an issue that had been around for a long time. This is a bug that caused a buffer overflow and affected security. You can see more information by searching for the code CVE-2019-7165 (by Alexandre Bartel) with which this vulnerability has been marked.
- In addition, a basic permission system has been added so that programs running within DOSBox cannot access the content of / proc, and this also has to do with security. The vulnerability has been marked as CVE-2019-12594, also discovered by Alexandre Bartel.
- Others bugs Presents that also affected security have been solved.
- And also fixed some issues related to rendering with OpenGL.
Now, the new DOSBox 074-2 version is more secure, although there are no differences in terms of new functions or other improvements. Additionally, the development team continues to work on the new version DOSBox 0.75 that we will see soon and that will also bring improvements.
