In versions prior to master-584-0a7ae07, the pickle .ckpt parser in src/model.cpp contained a heap buffer overflow vulnerability in the BINUNICODE opcode handler. The issue was caused by sign confusion on the opcode length field. A crafted .ckpt file could trigger memcpy with a very large length derived from a negative signed value, causing immediate heap corruption.\nThe issue has been resolved in version master-584-0a7ae07. If developers are unable to immediately update their applications they can work around this issue by only loading .ckpt checkpoint files from trusted sources and preferring trusted model sources and safer formats such as .safetensors where possible."}, {"lang": "es", "value": "stable-diffusion.cpp es una biblioteca pura de C/C++ para ejecutar inferencia de modelos de difusi\u00f3n (Stable Diffusion, Flux, Wan, Qwen Image, Z-Image, y m\u00e1s).
