AI-suggested
A fix is available in stable-diffusion.cpp version master-584-0a7ae07. Users and developers should upgrade to this version to remediate the vulnerability. If immediate upgrade is not possible, do not load .ckpt checkpoint files from untrusted sources. Prefer trusted model sources and safer formats such as .safetensors to avoid exposure to this vulnerability.
Description
A heap buffer overflow vulnerability exists in the pickle .ckpt parser of stable-diffusion.cpp prior to version master-584-0a7ae07. The flaw occurs due to missing validation when parsing newline-delimited fields, allowing a crafted .ckpt file without the expected newline to cause heap corruption. This vulnerability requires loading a malicious .ckpt file from an untrusted source. The issue has been fixed in version master-584-0a7ae07. Until updated, users should avoid loading .ckpt files from untrusted sources and prefer safer formats like .safetensors.
