Summary0002839: Rig Control: bad parameters to mbstowcs_s() cause crash at startup
DescriptionAt startup, the Rig Control applciation tries to handle the user's license. It passes a block of data to a thread, which unpacks that data and converts one of the strings in it from multi-byte to wide characters. The call to mbcstowcs_s() is incorrectly coded; it has no defense against strings that are unexpectedly too long, and crashes in that situation--which causes the application not to start without any error message for the user.

No specific repro is provided as this issue was discovered by examining crash dumps reported on the Microsoft Dev Center Dashboard. A spreadsheet with the populated stack dump is attached for reference.

This doesn't seem to be a particularly common crash type; less than 1% of the time ... but it's there, so lets fix it.
TagsNo tags attached.
