Hello,
We have released an update!
This is a security focused 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.
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.
Have Fun,
DOSBox Project Administrators

Hello,
We release a maintenance release for DOSBox 0.74, which solves the
following problems:
- Windows: Fix auto/max cycles algorithm on Windows 7, which helps with
stuttering audio.
- Mac OS X: Bring a 64 bit version and improve performance.

- Reduce overhead of the Mac version with a lot. Results in a speed
increase.
- Replace NV_PixelDataRange with the more common ARB_PixelBufferObject
extension. Should help with output=opengl.

- Add patches to work better when called by WINE:
- support WINE style namemangling.
- allow Z:\ to be moved to a different drive.
- Try to fix stuttering audio with opengl output on Linux. (or at least
improve it. Linux users might need to increase the prebuffer option a
bit)

SDL
without X11.

- Writing out the index too often. (slowdown with longer captures)
- Not being aware of when only the refresh rate changed.
- Fix call order when bitshifting the return order (VS C /O2 builds).
- Fix sign-extension error in S3 draw funcion, i.e. win3.1 analog clock.
- Fix expanddot not caring about the size of the inputbuffer.
- Some fixes for the debugger related to starting a program through
debug.com.

- Fix off by one display size calculation errors with very large displays.
- Fix out of bounds access the unused byte in the 32 bit colour value of
the
hardware mouse cursor pixel was affected.
- Fix depreciated warnings on Mac, allow soundfont loading for coreaudio.
- Keep repeating a pressed key if another key was unpressed.
- Fix crash on OS X related to putting junk in the titlebar.

Hello, After a long time DOSBox 0.60 is finally released. The most new important feature: basic protected mode support. A full changelog is included below. Please note that the configuration files have changed: not all options present in 0.58 will work in 0.60. Dosbox is still a full emulator. So games designed for a pentium are very very very slow. This version has the same problems with non-us keyboards as the 0.58 release. To fix this: 1. either change you keyboard layout to us. 2. try another key (for \ use /) 3. put the commands with in the configfile We've update the homepage as well so it can support more than one version of dosbox :) Have Fun!
