Comment 3 Riccardo Schirone 2019-01-30 10:48:24 UTC
When opening Sinar raw images that enable filters, the image data are updated in the wrong way in libraw_cxx.cpp:open_datastream(), causing an heap-based buffer overflow in raw2image() function later on.

Comment 5 Debarshi Ray 2019-02-01 13:51:06 UTC
Should be fixed in LibRaw-0.19.3.
