Description

As per the upstream advisory: "The Poppler library, by default, uses a private implementation of reading and rendering images. There is a compilation option for libjpeg support, but the flag is not enabled by default. This private implementation contains assumptions about the JPEG file headers that can lead to heap corruption when broken." However the version of poppler library shipped with Red Hat Enterprise Linux and Fedora use the system libjpeg library, therefore they are not affected by this flaw. |
