aa602fd107 Fix integer overflow in large file test 2019-01-07 08:49:14 -05:00

837dcf8fc2 Don't call assert while checking linearization data (fixes #209, #231) 
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.

d0e99f195a More robust handling of type errors 
Give objects descriptions and context so it is possible to issue
warnings instead of fatal errors for attempts to access objects of the
wrong type.

a8c93bd324 Push QPDF member variables into a nested class 
Pushing member variables into a nested class enables addition of new
member variables without breaking binary compatibility.

9744414c66 Enable finer grained control of stream decoding 
This commit adds several API methods that enable control over which
types of filters QPDF will attempt to decode. It also adds support for
/RunLengthDecode and /DCTDecode filters for both encoding and
decoding.

296b679d6e Implement findFirst and findLast in InputSource 
Preparing to refactor some pattern searching code to use these instead
of their own memchr loops. This should simplify the code that replaces
PCRE.

ac9c1f0d56 Security: replace operator[] with at 
For std::string and std::vector, replace operator[] with at.  This was
done using an automated process.  See README.hardening for details.

e19eb579b2 Replace some assertions with std::logic_error 
Ideally, the library should never call assert outside of test code,
but it does in several places.  For some cases where the assertion
might conceivably fail because of a problem with the input data,
replace assertions with exceptions so that they can be trapped by the
calling application.  This commit surely misses some cases and
replaced some cases unnecessarily, but it should still be an
improvement.

0bfe902489 Security: avoid pre-allocating vectors based on file data 
In places where std::vector<T>(size_t) was used, either validate that
the size parameter is sane or refactor code to avoid the need to
pre-allocate the vector.

3eb4b066ab Security: better bounds checks for linearization data 
The faulty code was only used during explicit checks of linearization
data.  Those checks are not part of normal reading or writing of PDF
files.

16051788ed Handle /Outlines dictionary being a direct object 
Even though this case is not valid according to the spec, it has been
seen, and caused an internal error.

getGeneration() with calls to getObjGen() where possible.

81e8752362 Use qpdf_offset_t in place of off_t in public APIs. 
off_t is used internally only when needed to talk to standard
libraries.  This requires that the "long long" type be supported by
the compiler.

5d4cad9c02 ABI change: fix use of off_t, size_t, and integer types 
Significantly improve the code's use of off_t for file offsets, size_t
for memory sizes, and integer types in cases where there has to be
compatibility with external interfaces.  Rework sections of the code
that would have prevented qpdf from working on files larger than 2 (or
maybe 4) GB in size.

a9987ab570 Fix a few compiler errors reported correctly my MSVC 9.0. 
Fix libtests test suites to pass on Windows, mostly by dealing with
ascii vs. binary and NL vs. CRNL change ($td->NORMALIZE_NEWLINES).
Convert some test suites to use fread instead of read.
PCRE.hh: define PCRE_STATIC if on Windows.
Provide cross-platform function for getting current time instead of
using time(0).
