Description D'juan McDonald (domhnall) 2019-01-05 17:06:44 UTC 
(https://nvd.nist.gov/vuln/detail/CVE-2018-20662):
In Poppler 0.72.0, PDFDoc::setup in PDFDoc.cc allows attackers to cause a denial-of-service (application crash caused by Object.h SIGABRT, because of a wrong return value from PDFDoc::setup) by crafting a PDF file in which an xref data structure is mishandled during extractPDFSubtype processing.

Upstream Patch: https://gitlab.freedesktop.org/poppler/poppler/commit/9fd5ec0e6e5f763b190f2a55ceb5427cfe851d5f  [reverted]

Maintainers please advise if this is fixed in tree.
Comment 2 Andreas Sturmlechner gentoo-dev 2019-03-27 20:55:55 UTC 
It isn't, as the upstream bug is still open and the original patch reverted for a good reason.
