Description Dhananjay Arunesh 2019-03-22 10:45:18 UTC
PDFDoc::markObject in PDFDoc.cc in Poppler 0.74.0 mishandles dict marking, leading to stack consumption in the function Dict::find() located at Dict.cc, which can (for example) be triggered by passing a crafted pdf file to the pdfunite binary.

Affects: fedora-all [bug 1691725]

Comment 3 Scott Gayou 2019-03-22 17:44:22 UTC
Red Hat Enterprise Linux 7 poppler (0.26.5) does not appear to be impacted by this stack overflow and completes without segfaulting. Versions before 0.26.5 do not appear impacted as well -- the code is quite different.
