Description

xpdf and kpdf do not properly validate the "loca" table in PDF files, which allows local users to cause a denial of service (disk consumption and hang) via a PDF file with a "broken" loca table, which causes a large temporary file to be created when xpdf attempts to reconstruct the information.
