"Several issues in poppler, a PDF rendering library, have been fixed.

CVE-2018-20650

A missing check for the dict data type could lead to a denial of
service.

CVE-2018-21009

An integer overflow might happen in Parser::makeStream.

CVE-2019-12493

A stack-based buffer over-read by a crafted PDF file might happen in
PostScriptFunction::transform because some functions mishandle tint
transformation.

For Debian 8 'Jessie', these problems have been fixed in version
0.26.5-2+deb8u11.

We recommend that you upgrade your poppler packages.

block directly from the DLA security advisory. Tenable has attempted
to automatically clean and format it as much as possible without
introducing additional issues."
