What to do
- See which version you have:
cargo tree -i pnet_packet(it also shows which of your dependencies pulls it in). - Update within your version requirement:
cargo update -p pnet_packet. If the fix is a newer major or minor than your requirement allows, raise it in Cargo.toml (for examplepnet_packet = "0.27.2") 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
As indicated by this issue, a buffer overrun is possible in the set_payload setter of the various mutable "Packet" struct setters. The offending set_payload functions were defined within the struct impl blocks in earlier versions of the package, and later by the packet macro.
Fixed in the packet macro by this PR.
