The American took the first set easily 6-1 against the unseeded Russian but then dropped her serve for the first time in the tournament, being broken three times as she lost the second set 6-3.
Williams, bidding for her first French Open title since 2002, was trailing 0-2 in the decider and fought off two break points that would have seen her slip to 0-3.
She then won six of the last seven games to secure victory in a shade under two hours and set up a semi-final clash against Italian fifth seed Sara Errani, the runner-up to Maria Sharapova last year.
Williams said: "It was very difficult and I am very tired. Svetlana played very well. She has won this tournament before so I am happy to get through such a tough match.
"Against Sara, it will be another tough match, she's a great fighter."
Errani reached the semi-finals for the second successive year with a 6-4 7-6 win over Polish fourth seed Agnieszka Radwanska.
The match featured 11 breaks of serve and last year's finalist had served for the match at 5-4 but Radwanska won to love.
The set went to a tie-break, which Errani took 8-6 to reach her third Grand Slam semi-final after she also went to the last four at the 2012 US Open.
"There was a lot of pressure because I have a lot of points to defend. That's a new experience for me," said Errani, who came into the French Open with a 0-28 record against top-five players.
