A while ago I tested qpdf with libfuzzer, all those issues have been fixed in 7.0.0 (latest is 7.1.1). Stack overflow due to endless recursion in QPDFTokenizer::resolveLiteral() https://github.com/qpdf/qpdf/issues/51 Another stack overflow / endless recursion in QPDFWriter::enqueueObject() https://github.com/qpdf/qpdf/issues/143 Stack out of bounds read in iterate_rc4() https://github.com/qpdf/qpdf/issues/147 heap out of bounds read (large) in Pl_Buffer::write https://github.com/qpdf/qpdf/issues/150 Hang due to a pdf xref loop: https://github.com/qpdf/qpdf/issues/149 Background: https://blog.fuzzing-project.org/59-Six-year-old-PDF-loop-bug-affects-most-major-implementations.html A quick check with the latst 7.1.1 with libfuzzer and asan revealed no further bugs. -- Hanno Böck https://hboeck.de/ mail/jabber: hanno@...eck.de GPG: FE73757FA60E4E21B937579FA5880072BBB51E42
