Yahoo cofounder and one-time (failed) CEO Jerry Yang is trying to take control of the company again.

He's trying to buy it.

There is a feud going on between Yang and Yahoo chairman Roy Bostock.

"Bostock is trying to keep Yang out," says a source close to the situation.

"It's playing out in meetings here."

Our source does not believe Yang has yet to find the capital needed.

Yang currently owns 3.63% of Yahoo. His fellow cofounder, and likely ally, David Filo, owns 5.80%.

Briefed on the details of this story a spokesman for the Yahoo board says "no comment."

Earlier today, activist hedge funder Daniel Loeb announced a 5.1% position in Yahoo and wrote a letter demanding that much of the company's board step down.

Earlier this week, Yahoo fired its CEO, Carol Bartz.
