Several issues have been found in libsdl2, a library for portable low level access to a video framebuffer, audio output, mouse, and keyboard. All issues are related to either buffer overflow, integer overflow or heap-based buffer over-read, resulting in a DoS or remote code execution by using crafted files of different formats.

For Debian 9 stretch, these problems have been fixed in version 2.0.5+dfsg1-2+deb9u1.

We recommend that you upgrade your libsdl2 packages.

For the detailed security status of libsdl2 please refer to its security tracker page at:
https://security-tracker.debian.org/tracker/libsdl2
