Code execution via crafted-file out-of-bounds read
Published Oct 10, 2025 · Updated Oct 10, 2025
Out-of-bounds read in Fuji Electric V-SFT 6.2.7.0 and earlier allows local users to execute code by opening a crafted V-SFT file. The VS6ComFile!CSaveData::delete_mem routine reads beyond an allocated memory boundary while parsing attacker-controlled file data. Exploitation requires user interaction to open the file and can also disclose information or cause the application to terminate abnormally.
