Security Fix(es):

* libjpeg: null pointer dereference in cjpeg (CVE-2016-3616)

* libjpeg-turbo: heap-based buffer over-read via crafted 8-bit BMP in get_8bit_row in rdbmp.c leads to denial of service (CVE-2018-14498)

* libjpeg-turbo: Divide By Zero in alloc_sarray function in jmemmgr.c (CVE-2018-11212)

* libjpeg: Segmentation fault in get_text_gray_row function in rdppm.c (CVE-2018-11213)

* libjpeg: Segmentation fault in get_text_rgb_row function in rdppm.c (CVE-2018-11214)

* libjpeg: "cjpeg" utility large loop because read_pixel in rdtarga.c mishandles EOF (CVE-2018-11813)
