Depends on what kind of exploitation you're talking about -- integer overflows can still cause out of memory conditions and crash the program, which is a denial-of-service vulnerability when talking about webapps.
But yes, memory-save languages like Rust are a massive help protecting against remote code execution. (unless said memory-safe language introduces its own category of RCE vulnerabilities, e.g. deserialization in Java)
