2020-10-22Obscure bug fix copying foreign streams in special cases (fixes #449)Jay Berkenbilt
Specifically, if a stream had its stream data replaced and had indirect /Filter or /DecodeParms, it would result in non-silent loss of data and/or internal error.

2020-10-18Stop using InputSource::unreadChJay Berkenbilt
2020-10-17Check integer overflow in resolveObjectsInStreamDean Scarff
Fixes a crash found by fuzzing.
2020-10-17Properly detect OPENSSL_IS_BORINGSSLDean Scarff
OPENSSL_IS_BORINGSSL is not actually set by configure, so it will be undefined until a BoringSSL header is included. Hence the #ifdef logic in QPDFCrypto_openssl.h would usually never apply. This still worked because evp.h transitively included BoringSSL's cipher.h and digest.h, but the latter are the correct (documented) headers. By re-ordering the includes, we can ensure the macro is defined when we use it. Also: fix case in the header guards.

Fixes qpdf/qpdf#450
2020-10-17Replace memchr with manual memory searchJames R. Barlow
On large files with predominantly \n line endings, memchr(..'\r'..) seems to waste a considerable amount of time searching for a line ending candidate that we don't need. On the Adobe PDF Reference Manual 1.7, this commit is 8x faster at QPDF::processMemoryFile().
