In the previous description it said there was a TOCTOU race but did not explain exactly what the problem was. I sat down with the CVE, reviewed its text, and created this explanation. This context should hopefully help people understand the actual risk as-such.

Incidentally, it also fixes the capitalization on the name of Redox OS.
