Description Laura Pardo 2018-09-03 19:37:58 UTC

A flaw was found in Xpdf 4.00. The XRef::fetch in XRef.cc allows remote attackers to cause a denial of service (stack consumption) via a crafted pdf file, related to AcroForm::scanField, as demonstrated by pdftohtml. NOTE: this might overlap CVE-2018-7453.
