"The following issues have been found in libsdl2-image, the image file
loading library.

CVE-2018-3977

Heap buffer overflow in IMG_xcf.c. This vulnerability might be
leveraged by remote attackers to cause remote code execution or denial
of service via a crafted XCF file.

CVE-2019-5052

Integer overflow and subsequent buffer overflow in IMG_pcx.c. This
vulnerability might be leveraged by remote attackers to cause remote
code execution or denial of service via a crafted PCX file.

CVE-2019-7635

Heap buffer overflow affecting Blit1to4, in IMG_bmp.c. This
vulnerability might be leveraged by remote attackers to cause denial
of service or any other unspecified impact via a crafted BMP file.

CVE-2019-12216, CVE-2019-12217, CVE-2019-12218, CVE-2019-12219,
CVE-2019-12220, CVE-2019-12221, CVE-2019-12222

Multiple out-of-bound read and write accesses affecting
IMG_LoadPCX_RW, in IMG_pcx.c. These vulnerabilities might be leveraged
by remote attackers to cause denial of service or any other
unspecified impact via a crafted PCX file.

For Debian 8 'Jessie', these problems have been fixed in version
2.0.0+dfsg-3+deb8u2.

We recommend that you upgrade your libsdl2-image packages.
