Copa America host Brazil had three goals ruled out and missed a series of chances as it was held 0-0 by Venezuela on Tuesday.
Roberto Firmino had a goal chalked off late in the first half after the referee awarded a foul against the host, before substitute Gabriel Jesus found the net on the hour mark only for a Video Assistant Referee (VAR) review to deem Firmino offside in the build-up.
Philippe Coutinho looked to have finally found the winner when he netted from close range but VAR intervened again.
Brazil leads the group on four points ahead of Peru, which beat Bolivia 3-1 earlier in the day and also has four points.
Bolivia scored its first goal in five games but it was not enough to give its first Copa America point as Peru came from behind to win 3-1 in Rio de Janeiro.
Bolivia had not scored since drawing 2-2 with Nicaragua in March but it took the lead after 28 minutes when Marcelo Moreno scored a VAR-assisted penalty.
Paolo Guerrero equalised for Peru on the stroke of half time when he rounded the keeper and slotted the ball into the empty net and the big Internacional striker turned provider 10 minutes into the second half when he crossed for Jefferson Farfan to nod home and put Peru ahead.
The results :
Group A : Bolivia 1 (Moreno 28) lost to Peru 3 (Guerrero 45, Farfan 55, Flores 90+6).
Brazil 0 drew with Venezuela 0 .
