DOSBox 0.74-3 has been released A new version has been released, with the focus on security: 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. Full changelog: Implement basic file access control for files available from within the emulation, so that programs running inside DOSBox can't access /proc (e.g. /proc/self/mem). (CVE-2019-12594) Unify unmounting code and add some protections against out of bound access when DOS_DRIVES is not 26. Use correct type for return value of strlen. Change scan3x to a bit brighter. Fix unitialized access to some isoDrive fields and improve stability when switching CD images. Small fix to hq3x. Fix 256 colour mode encoding in zmbv.dll. Some small aliassing fix. Change SET to check the size of the MCB when adding variables. Fixes hangs with Norton Commander. Check buffer length before doing tab completion. Correct buffer overflow with very long lines in bat files. (CVE-2019-7165) Correct the boundary check for the internal programs array. Increase stability in max cycles mode by increasing the lower bound. Fix command prompt in windows 3.11 with dynrec core. Fix Win64 dynrec core. Always clear buffers before drawing in OpenGL mode. Fixes artifacts with drivers that have more than 2 buffers and overlays. Fix red border that appeared when scaling the image in OpenGL mode with Nvidia on Linux and Mac. Change default output to opengl on Mac, as surface is very slow there in 64 bit. Add workaround for the mouse unlocking problem with X.org 1.20.1. Fix table access when USE_FULL_TLB is undefined (non-default configuration). Several fixes to prevent compilation errors. Update Visual studio file to fix missing files from 0.74-2. In an ideal world 0.75 would have been released already, but some bugs took way longer than expected as well as real life demanding a lot of attention. It's still being worked on.
