2017-05-26Avoid dangling encrypt dict pointer in CPDF_ParserTom Sepez
CPDF_Parser::StartParse should release the current encrypt dict before trashing it by calling RebuildCrossRef() at cpdf_parser.cpp:195. This gives rise to the pattern that calls to ReleaseEncryptHandler() are followed by SetEncryptDict(nullptr), so just move the later into the former.

2017-05-23Make CPDF_ImageCacheEntry retain CPDF_ImageTom Sepez
CPDF_PageRenderCache::m_ImageCache is a map from streams to an image cache entry containing a clump of data associated with the stream. Oddly, the clump includes the stream key (which we already have in order to get to the clump), but worse doesn't ensure the existence of the CPDF_Image object which (maybe) owns the stream key in question. So replace the stream with a retained ptr to the image. Also renamed an unrelated member to avoid confusion with the CPDF_Object in play.

2017-05-16Introduce CFX_UnownedPtr to detect lifetime inversion issues.Tom Sepez
There are places where an object "child" has a raw pointer back to object "owner" with the understanding that owner will always outlive child. Violating this constraint can lead to use after free, but this requires finding two paths: one that frees the objects in the wrong order, and one that uses the object after the free. The purpose of this patch is to detect the constraint violation even when the second path is not hit. We create a template that is used in place of TYPE*. It's dtor, when a memory tool is present, goes out and probes the first byte of the object to which it points. Used in "child", this allows the memory tool to prove that the "owner" is still alive at the time the child is destroyed, and hence the constraint is never violated.
