"The cjpeg utility in libjpeg allows remote attackers to cause a denial
of service (NULL pointer dereference and application crash) or execute
arbitrary code via a crafted file.(CVE-2016-3616)

A divide by zero vulnerability has been discovered in libjpeg-turbo in
alloc_sarray function of jmemmgr.c file. An attacker could use this
vulnerability to cause a denial of service via a crafted file.

CVE-2018-11212)

An out-of-bound read vulnerability has been discovered in
libjpeg-turbo when reading one row of pixels of a PGM file. An
attacker could use this flaw to crash the application and cause a
denial of service.(CVE-2018-11213)

An out-of-bounds read vulnerability has been discovered in
libjpeg-turbo when reading one row of pixels of a PPM file. An
attacker could use this flaw to crash the application and cause a
denial of service.(CVE-2018-11214)

libjpeg 9c has a large loop because read_pixel in rdtarga.c mishandles
EOF.(CVE-2018-11813)

get_8bit_row in rdbmp.c in libjpeg-turbo through 1.5.90 and MozJPEG
through 3.3.1 allows attackers to cause a denial of service
(heap-based buffer over-read and application crash) via a crafted
8-bit BMP in which one or more of the color indices is out of range
for the number of palette entries.(CVE-2018-14498)");
