"An update for libjpeg-turbo is now available for Red Hat Enterprise
Linux 7.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

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)

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

For more details about the security issue(s), including the impact, a
CVSS score, acknowledgments, and other related information, refer to
the CVE page(s) listed in the References section.
