2017-03-28Refcount all CFX_DIBSources (and subclasses) all the time.Tom Sepez
There are currently several ownership models for these objects, including ad-hoc logic for sharing and deletion, and the now-redundant CFX_DIBitmapRef externally-counted handle to the DIBs. Replace them all with the internal refcount scheme.

2017-03-01Create virtual codec APIs so chrome/fuzzers can link separatelyTom Sepez
The one step to make an actual concrete class is conditionalized in fpdfview and is unconditional in the fuzzer. Also replace the clumsy C-style callbacks with a delegate interface as long as we are making new interfaces.

2017-01-27Limit parsing recursion levels in CPDF_StreamParserNicolas Pena
We currently only limit the array recursion levels. This recursion level may also be reset when parsing. This is insufficient to protect against stack overflows.

2017-01-26Fix CSS fuzzer input sizeDan Sinclair
Currently we use the size provided by clusterfuzz when initializing the css syntax parser. This maybe incorrect as the CFX_WideString may have a different count after converting to UTF. Use the wide string length instead of the provided size. We need to guard against strings that convert to blank when doing the wide conversion so add an early exit.
