Summary
The CImg library, a C++ image-processing header used by software that loads BMP images, is affected by this flaw. A specially crafted BMP file with an oversized width can cause the program to read past the bounds of heap memory, leading to crashes or exposure of memory contents in the decoded image.
Summarized by anthropic/claude-haiku-5.5. Verify details against the original sources.
Read the original description
CImg through 4.0.6 contains a heap out-of-bounds read vulnerability in the _load_bmp() function of CImg.h caused by an integer overflow in the row byte count. Attackers can supply a crafted BMP file with a large header width that wraps dx_bytes, causing crashes or heap memory disclosure into the decoded image.
