Technical details

The vulnerability is an out-of-bounds read (CWE-125) in the VS6EditData component's CDataRomErrorCheck::MacroCommandCheck function. A local attacker must craft a malicious V7 project file and convince a user to open it, triggering memory access beyond allocated bounds. A successful exploit can leak sensitive information or lead to arbitrary code execution with the privileges of the user running V-SFT.
