HIGH 7.5EPSS 3.67%

Does this matter?

High impact if exploited, but EPSS currently rates exploitation as unlikely (3.67%). Schedule it in the normal patch cycle and watch for a rise in EPSS or a public exploit.

Description

LibRaw before 0.20-RC1 lacks a thumbnail size range check. This affects decoders/unpack_thumb.cpp, postprocessing/mem_image.cpp, and utils/thumb_utils.cpp. For example, malloc(sizeof(libraw_processed_image_t)+T.tlength) occurs without validating T.tlength.
