DOSBox v0.74-3




Nouvelle version pour cet émulateur MS-DOS vous permettant de rejouer à d'anciens titres parus sur PC dont certains sont disponibles dans nos diverses sections abandonwares.

Citation
A security release for DOSBox 0.74:

- Fixed that a very long line inside a bat file would overflow the parsing buffer. (CVE-2019-7165 by Alexandre Bartel)
- Added a basic permission system so that a program running inside DOSBox can't access the contents of /proc (e.g. /proc/self/mem) when / or /proc were (to be) mounted. (CVE-2019-12594 by Alexandre Bartel)
- Several other fixes for out of bounds access and buffer overflows.
- Some fixes to the OpenGL rendering.

The game compatibility should be identical to 0.74 and 0.74-2.
It's recommended to use config -securemode when dealing with untrusted files.


Ideally, 0.75 should have been released by now, but some bugs took a lot longer than expected.
