Freshness: upstream tracker timestamp is available; use API updated time as primary recency signal.
CVE-2018-8100 negligible priority: Ubuntu including 4 source packages (ipe, libextractor, poppler, xpdf), 80 status rows across 20 suites (artful, bionic, cosmic, disco, eoan, focal, groovy, hirsute, impish, jammy, kinetic, lunar, mantic, noble, oracular, plucky, questing, trusty, upstream, xenial): ignored 30, not-affected 30, needs-triage 10, DNE 5, needed 5.
The JPXStream::readTilePart function in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service (heap-based buffer overflow and application crash) or possibly have unspecified other impact via a specific pdf file, as demonstrated by pdftohtml.
