strcpy()
with an argument that specifically contains multiple null bytes. strcpy()
only copies a single terminating null character into the target buffer instead of copying the required double null bytes in the addKeysToRegistry()
function. As a consequence, a garbage registry entry can be created. The additional arsize
parameter is erroneously set to contain two null bytes and the following call to RegSetValueEx()
claims to be passing in a multi-string value, though this may not be true.
