V-SFT v6.2.5.0 and earlier contains an issue with free of pointer not at start of buffer in VS6EditData.dll!CWinFontInf::WinFontMsgCheck function. Opening specially crafted V7 or V8 files may lead to crash, information disclosure, and arbitrary code execution.
The product calls free() on a pointer to a memory resource that was allocated on the heap, but the pointer is not at the start of the buffer.
The product attempts to return a memory resource to the system, but it calls the wrong release function or calls the appropriate release function incorrectly.
