Kerentanan Memory Allocation with Excessive Size Value. Skor CVSS 3.1 5.5 (Medium) menurut github.com.

Deskripsi (NVD)

CImg Library is a C++ library for image processing. Prior to commit c3aacf5, the nb_colors field read from the BMP file header is used directly to compute an allocation size without validating it against the remaining file size. A crafted BMP file with a large nb_colors value triggers an out-of-memory condition, crashing any application that uses CImg to load untrusted BMP files. This issue has been patched via commit c3aacf5.
