Description D'juan McDonald (domhnall) 2019-01-05 17:06:44 UTC
In Poppler 0.72.0, PDFDoc::setup in 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:  [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.
