Gallas' current contract expires in the summer and negotiations regarding fresh terms were recently put on hold by Wenger.
The Frenchman said: "No, there is no news. There's no impasse and no agreement."
Gallas' fellow centre-half Campbell is also out of contract in the summer, having signed a short-term deal upon rejoining Arsenal in January.
Wenger added: "I don't know yet. I don't want officially to commit on that because I don't know what I will do.
"At the start he came to ask me if I could help him to get fit. Now he plays tomorrow against Tottenham. So that doesn't mean he has signed a contract for next season.
"Maybe he will not want to play, I don't know what I will want to do. At the moment we have short-term targets."
