What to do
- See which version you have:
cargo tree -i cookie(it also shows which of your dependencies pulls it in). - Update within your version requirement:
cargo update -p cookie. If the fix is a newer major or minor than your requirement allows, raise it in Cargo.toml (for examplecookie = "0.7.6") 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
Affected versions of this crate use the time crate and the method Duration::seconds to parse the Max-Age duration cookie setting. This method will panic if the value is greater than 2^64/1000 and less than or equal to 2^64, which can result in denial of service for a client or server.
This flaw was corrected by explicitly checking for the Max-Age being in this integer range and clamping the value to the maximum duration value.
