The libjpeg-turbo packages contain a library of functions for manipulating JPEG images. They also contain simple client programs for accessing the libjpeg functions. These packages provide the same functionality and API as libjpeg but with better performance.

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)
