* Allow to use global LZO library instead of miniLZOTobias Junghans2018-11-221-0/+4
| | | | | The complete LZO library nowadays is installed on many systems so we can optionally make use of it and omit internal miniLZO implementation.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - As with the encoder, the decoder now uses the TurboJPEG wrapper, which allows it to decode JPEG images directly into the framebuffer. This eliminates a buffer copy (CopyRectangle()) as well as the expensive RGB pixel conversion in DecompressJpegRectBPP(). The TurboJPEG wrapper performs RGB pixel conversion more optimally, and only when necessary (it uses the libjpeg-turbo colorspace extensions when available, in order to avoid RGB conversion.) - The other Tight subencoding types are also now decoded directly into the framebuffer, which eliminates buffer copies. - The Tight decoder now supports the rfbTightNoZlib extension, which allows the server to bypass zlib compression when Compression Level 0 is selected. The encoder already supports this extension. Passing the data stream through zlib when Compression Level 0 is selected needlessly wastes CPU time, since all zlib is doing is copying the data internally into its own structures.

* Set trueColour flag to 1 instead of 255dborth2017-04-041-1/+1
| | | | | | | | | | | It turns out some server implementations (namely VMware ESXi 6.5) expect 1 as the only non-zero value for the SetPixelFormat message whereas the protocol states every non-zero value is valid (https://github.com/rfbproto/rfbproto/blob/master/rfbproto.rst#setpixelformat). Anyway, setting this to 1 shouldn't hurt. Fixes #141

* | Fix heap overflow in the ultra.c decoderJosef Gajdusek2016-11-141-4/+4
| | | | | | | | | | | | The Ultra type tile decoder does not use the _safe variant of the LZO decompress function, which allows a maliciuous server to overwrite parts of the heap by sending a larger-than-specified LZO data stream.
* | Fix heap overflows in the various rectangle fill functionsJosef Gajdusek2016-11-141-0/+24
|/ | | | | | Altough rfbproto.c does check whether the overall FramebufferUpdate rectangle is too large, some of the individual encoding decoders do not, which allows a malicious server to overwrite parts of the heap.
