How to fix?

Upgrade Centos:7 poppler-demos to version 0:0.26.5-42.el7 or higher.

NVD Description

Note: Versions mentioned in the description apply only to the upstream poppler-demos package and not the poppler-demos package as distributed by Centos. See How to fix? for Centos:7 relevant fixed versions and status.

The JPXStream::init function in Poppler 0.78.0 and earlier doesn't check for negative values of stream length, leading to an Integer Overflow, thereby making it possible to allocate a large memory chunk on the heap, with a size controlled by an attacker, as demonstrated by pdftocairo.
