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.
2020-10-21Protect numeric conversion against user's locale (fixes #459)Jay Berkenbilt

2020-04-06Allow propagation of errors and retry through StreamDataProviderJay Berkenbilt

2019-10-22Add QPDF::getXRefTable()Masamichi Hosoda
2019-10-22Exclude signature dictionary from compressible objectsMasamichi Hosoda
It seems better not to compress signature dictionaries. Various PDF digital signing tools, including Adobe Acrobat Reader DC, do not compress signature dictionaries. Table 8.93 "Entries in a signature dictionary" in PDF 1.5 reference describes that /ByteRange in the signature dictionary shall be used to describe a digest that does not include the signature value (/Contents) itself. The byte ranges cannot be determined if the dictionary is compressed.

2019-08-27Seek in two stages to avoid overflowJay Berkenbilt
When seeing to a position based on a value read from the input, we are prone to integer overflow (fuzz issue 15442). Seek in two stages to move the overflow check into the input source code.

2019-06-21Fix sign and conversion warnings (major)Jay Berkenbilt
This makes all integer type conversions that have potential data loss explicit with calls that do range checks and raise an exception. After this commit, qpdf builds with no warnings when -Wsign-conversion -Wconversion is used with gcc or clang or when -W3 -Wd4800 is used with MSVC. This significantly reduces the likelihood of potential crashes from bogus integer values. There are some parts of the code that take int when they should take size_t or an offset. Such places would make qpdf not support files with more than 2^31 of something that usually wouldn't be so large. In the event that such a file shows up and is valid, at least qpdf would raise an error in the right spot so the issue could be legitimately addressed rather than failing in some weird way because of a silent overflow condition.
2019-06-15Eliminate one potential integer overflowJay Berkenbilt
There are more to handle, but this resolves an issue already caught by oss-fuzz.

* [bcc32 Error] QPDF.cc(375): E2268 Call to undefined function 'atof' Full parser context QPDF.cc(358): parsing: void QPDF::parse(const char *) * [bcc32 Error] QPDFTokenizer.cc(183): E2268 Call to undefined function 'strtol' Full parser context QPDFTokenizer.cc(163): parsing: void QPDFTokenizer::resolveLiteral() * [bcc32 Error] pdf-split-pages.cc(52): E2268 Call to undefined function 'exit' Full parser context pdf-split-pages.cc(50): parsing: void usage() * PR #295: Including "cstdlib" should be replaced with "stdlib.h" to be more consistent. At the same time I changed the order of the surrounding includes to reflect alphabetical order, because at some files this already have been the case.

2019-01-29Clarify documentation for copyForeignObject regarding pagesJay Berkenbilt
Make explicit that copyForeignObject can be used on page objects and will copy them properly but not update the pages tree.
2019-01-12Allow adding the same page more than once in --pages (fixes #272)Jay Berkenbilt
2019-01-11Add QPDF::setImmediateCopyFromJay Berkenbilt
2019-01-07Update version to 8.3.0Jay Berkenbilt
2019-01-07Exercise out of scope original pdf for copyForeignObjectJay Berkenbilt
2019-01-07Mostly don't require original QPDF for copyForeignObject (fixes #219)Jay Berkenbilt
The original QPDF is only required now when the source QPDFObjectHandle is a stream that gets its stream data from a QPDFObjectHandle::StreamDataProvider.
2019-01-07Make a static version of QPDF::pipeStreamDataJay Berkenbilt
This is in preparation of being able to pipe a stream's data without keeping a copy of its containing qpdf object.
2019-01-07Create an application-scope unique ID for each QPDF objectJay Berkenbilt
Use this instead of QPDF* as a map key for object_copiers.
2019-01-06Move encryption parameters into a classJay Berkenbilt
2019-01-04Don't call assert while checking linearization data (fixes #209, #231)Jay Berkenbilt
Instead of calling assert for problems found during checking linearization data, throw an exception which is later caught and issued as an error. Ideally we would handle errors more robustly, but this is still a significant improvement.
2019-01-04Fix dangling references (fixes #240)Jay Berkenbilt
On certain operations, such as iterating through all objects and adding new indirect objects, walk through the entire object structure and explicitly resolve any indirect references to non-existent objects. That prevents new objects from springing into existence and causing the previously dangling references to point to them.
2019-01-03Fix seg fault on empty xref stream (fixes #263)Jay Berkenbilt
