halacha - Can one rely on halal combined with vegetarian labels?

i understand that halal can not be trusted for meat, but what about items that are certified halal and certified vegetarian? There are many vegetarian curry pastes and other spice pastes that can be found that are both certified halal and vegetarian but don't have a kosher hechsher.

Pastes are in sealed tin cans. They say they are processed in facilities that process nuts and sesame. There is no milk or dairy in them.
