Synopsis

The remote Debian host is missing a security update.

Description

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

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

Solution

Upgrade the affected packages.
