The vulnerability stems from the usage of a 32-bit arithmetic to calculate the pixel buffers when decoding the raw image file, which may end up overflowing when processing user controlled images as input. The calculation result is further used within 64-bit boundary checking however the proper cast is missing and the result value is used to allocate the buffer from memory, when the overflow happens the function may start writing outside of the expected memory boundary leading to data corruption.\nRed Hat Product Security has rated this vulnerability as having a Moderate impact, despite the possibility of arbitrary code execution due to the heap-based buffer overflow, as the user needs to be tricked to process a maliciously crafted image or LibRaw needs to be exposed to the network and accept untrusted data as input.", "threat_severity": "Moderate"}
