CVE-2016-3616 The cjpeg utility in libjpeg allowed remote attackers to cause a denial of service (NULL pointer dereference and application crash) or execute arbitrary code via a crafted file. This issue got fixed by the same patch that fixed CVE-2018-11213 and CVE-2018-11214.

The issue has been resolved by a boundary check. CVE-2018-11212 The alloc_sarray function in jmemmgr.c allowed remote attackers to cause a denial of service (divide-by-zero error) via a crafted file. The issue has been addressed by checking the image size when reading a targa file and throwing an error when image width or height is 0.
