That is what I was told - it was the glue. The areas where it happened do not receive direct sunlight so I think mine must be the glue. Mine also happened where a simple cotton throw rug laid, this cotton rug had no backing. It begin to show up about 6 months after we laid new vinyl in our kitchen. I called the company that sold and installed it and they said it was the glue. They came out, torn up the vinyl, put new vinyl down with a different glue, but now 17 years later the "new vinyl" is beginning to show some yellow areas.
