The bzip2 crate before 0.4.4 for Rust allow attackers to cause a denial of service via a large file that triggers an integer overflow in mem.rs. NOTE: this is unrelated to the https://crates.io/crates/bzip2-rs product.
The product performs a calculation that can produce an integer overflow or wraparound when the logic assumes that the resulting value will always be larger than the original value. This occurs when an integer value is incremented to a value that is too large to store in the associated representation. When this occurs, the value may become a very small or negative number.
