Assigning to our registered sdl2  maintainer.

I backported the fixes for SDL 1.2 in bug 24496.

I'll wait for now with SDL2 as most of the patches haven't been accepted/merged upstream yet, and Fedora hasn't tried to cherry-pick them either. Upstream is usually relatively quick to respond to security vulnerabilities, so it might be worth waiting for 2.0.10 fixing those.

SUSE has issued an advisory for this on April 15:
http://lists.suse.com/pipermail/sle-security-updates/2019-April/005337.html

For the reference, still waiting for 2.0.10 which should be right around the corner: https://discourse.libsdl.org/t/sdl-2-0-10-prerelease/26300

Cauldron seems fixed with latest 2.0.10 release!

So Rémi can you look for mga7 and mga6, please?

David pointed out to me that 2.0.10 also fixes CVE-2019-13616:

This is another one where the ASAN POC files need certain test utilities, like testsprite.

Failed attempt at compiling testsprite.c.

I'm guessing that version of testsprite is for SDL 1.2.

Quite right David.  I had just seen that.

The RedHat link leads to discussions covering versions 1.2 onwards, centring on audio/SDL_wave.c.

Found the source for loopwave.c at https://android.googlesource.com/platform/external/qemu/+/android-4.2.2_r1.2/distrib/sdl-1.2.15/test/loopwave.c
It needed a little editing before compiling.
$ gcc -o loopwave -I/usr/include/SDL2 -lSDL2 loopwave.c
loopwave.c: In function ‘main’:
loopwave.c:88:60: warning: passing argument 1 of ‘SDL_GetAudioDeviceName’ makes integer from pointer without a cast [-Wint-conversion]
  printf("Using audio driver: %s\n", SDL_GetAudioDeviceName(name, 32));
                                                            ^~~~
In file included from /usr/include/SDL2/SDL.h:36,
                 from loopwave.c:12:
/usr/include/SDL2/SDL_audio.h:359:37: note: expected ‘int’ but argument is of type ‘char *’
 extern DECLSPEC const char *SDLCALL SDL_GetAudioDeviceName(int index,
                                     ^~~~~~~~~~~~~~~~~~~~~~

Despite these errors it produced a viable binary file.
Not entirely confident about the API here after seeing the troubles with testsprite.c.  Duh!  Just noticed that the link specifically indicates sdl-1.2.15, so cancelling all the POC tests, which involved loopwave, testsprite and graywin.  Four hours work down the drain.

mga7, x86_64

Ignoring the POC because the test programs are not readily available for SDL2.

Updated all the packages.

The libraries are required by a considerable number of games and utilities such as mpv.  Running strace while playing audio and video tracks with mpv shows that libSDL2-2.0 is opened successfully.

Installing neverball pulled in lib64sdl2_ttf2.0_0 which was heavily used during play.  Game working fine.

$ strace -o trace fallingtime
SDL initialisation succeeded
SDL_CreateWindow succeeded
SDL_CreateRenderer succeeded
Mix_OpenAudio succeeded
TTF_Init succeeded

The trace showed several SDL2 libraries being used.

Started blender and carried out a few primitive operations.  SDL2 library was opened.

It looks like everything is OK for 64bits.

Whiteboard: MGA6TOO => MGA6TOO MGA7-64-OK

mga6, x86_64

Updated the packages.

$ urpmq --whatrequires mingw64-SDL2 | sort -u
mingw64-SDL2
mingw64-SDL2_image
mingw64-SDL2_mixer
mingw64-SDL2_net
mingw64-SDL2-static

Most of the mingw programs under /bin look like programming tools so we shall skip those.
pinball and neverball work fine.
Played music and video tracks with mpv.

blender opens and responds to 'links'.
Recover Last Session indicates that there was none - correct.
Blender Render shows a 3D cube, which can be manipulated.  Tried duplication, moving and rotation.  Working fine.

OK for 64bits.

Validating this.  Advisory in comment 8 - needs to be pushed to SVN.  My SSH setup does not allow me to do it.

Len, the update validation is not complete until you put "validated_update" in the Keywords box. For backports, ""validated_backport" is used.

An update for this issue has been pushed to the Mageia Updates repository.
