CVE-2019-12360 fixed by [1]
A stack-based buffer over-read exists in FoFiTrueType::dumpString in fofi/FoFiTrueType.cc in Xpdf 4.01.01. It can, for example, be triggered by sending crafted TrueType data in a PDF document to the pdftops tool. It might allow an attacker to cause Denial of Service or leak memory data into dump content.

CVE-2019-17064 fixed by [2]
Catalog.cc in Xpdf 4.02 has a NULL pointer dereference because Catalog.pageLabels is initialized too late in the Catalog constructor.
