The update of libsdl2 released as DLA 1714-1 led to several regressions, as reported by Avital Ostromich. These regressions are caused by libsdl1.2 patches for CVE-2019-7637, CVE-2019-7635, CVE-2019-7638 and CVE-2019-7636 being applied to libsdl2 without adaptations.

For Debian 8 ‘Jessie’, this problem has been fixed in version 2.0.2+dfsg1-6+deb8u2.

We recommend that you upgrade your libsdl2 packages.

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.
