A NULL pointer dereference in JPXStream::fillReadBuf in JPXStream.cc in xpdf 4.00 allows attackers to launch denial of service via a specific pdf file, as demonstrated by pdftohtml.
Does this matter?
Lower severity and a low EPSS score (0.79%). Track it; it rarely justifies an emergency change on its own.
