What to do
- See which version you have:
cargo tree -i av-data(it also shows which of your dependencies pulls it in). - Update within your version requirement:
cargo update -p av-data. If the fix is a newer major or minor than your requirement allows, raise it in Cargo.toml (for exampleav-data = "0.3.0") or update the dependency that pulls it in. - Check again with
cargo audit, or paste your Cargo.lock into our Cargo.toml checker.
Details from the advisory
fn Frame::copy_from_raw_parts() is a safe API that can take a raw pointer and dereference it. It is possible to read arbitrary memory address with an arbitrarily fed pointer. This allows the safe API to access & read arbitrary address in memory. Feeding an invalid memory address pointer to the API may also cause the program to segfault.
The flaw was corrected in https://github.com/rust-av/rust-av/pull/137, by removing the API fn Frame::copy_from_raw_parts().
