Comment 3 Huzaifa S. Sidhpurwala 2020-06-01 05:32:49 UTC

Statement:

libEMF is a C/C++ library which provides a drawing toolkit based on ECMA-234. The general purpose of this library is to create vector graphics files on POSIX systems which can be imported into OpenOffice.org or LibreOffice. Programs compiled with libEMF, output ECMA-234 graphics files locally which can be then imported into desktop applications. Therefore this denial-of-service flaw can only be triggered via maliciously written applications compiled with libEMF.
