In the standard library in Rust before 1.52.0, the Zip implementation calls __iterator_get_unchecked() more than once for the same index (under certain conditions) when next_back() and next() are used together. This bug could lead to a memory safety violation due to an unmet safety requirement for the TrustedRandomAccess trait.
In the standard library in Rust before 1.52.0, the Zip implementation can report an incorrect size due to an integer overflow. This bug can lead to a buffer overflow when a consumed Zip iterator is used again.
Cargo prior to Rust 1.26.0 may download the wrong dependency if your package.toml file uses the `package` configuration key. Usage of the `package` key to rename dependencies in `Cargo.toml` is ignored in Rust 1.25.0 and prior. When Rust 1.25.0 and prior is used Cargo may download the wrong dependency, which could be squatted on crates.io to be a malicious package. This not only affects manifests that you write locally yourself, but also manifests published to crates.io. Rust 1.0.0 through Rust 1.25.0 is affected by this advisory because Cargo will ignore the `package` key in manifests. Rust 1.26.0 through Rust 1.30.0 are not affected and typically will emit an error because the `package` key is unstable. Rust 1.31.0 and after are not affected because Cargo understands the `package` key. Users of the affected versions are strongly encouraged to update their compiler to the latest available one. Preventing this issue from happening requires updating your compiler to be either Rust 1.26.0 or newer. There will be no point release for Rust versions prior to 1.26.0. Users of Rust 1.19.0 to Rust 1.25.0 can instead apply linked patches to mitigate the issue.
The Rust Programming Language Standard Library 1.18.0 and later is affected by: CWE-200: Information Exposure. The impact is: Contents of uninitialized memory could be printed to string or to log file. The component is: Debug trait implementation for std::collections::vec_deque::Iter. The attack vector is: The program needs to invoke debug printing for iterator over an empty VecDeque. The fixed version is: 1.30.0, nightly versions after commit b85e4cc8fadaabd41da5b9645c08c68b8f89908d.
Rust Programming Language Rust standard library version Commit bfa0e1f58acf1c28d500c34ed258f09ae021893e and later; stable release 1.3.0 and later contains a Buffer Overflow vulnerability in std::collections::vec_deque::VecDeque::reserve() function that can result in Arbitrary code execution, but no proof-of-concept exploit is currently published.. This vulnerability appears to have been fixed in after commit fdfafb510b1a38f727e920dccbeeb638d39a8e60; stable release 1.22.0 and later.
The Rust Programming Language rustdoc version Between 0.8 and 1.27.0 contains a CWE-427: Uncontrolled Search Path Element vulnerability in rustdoc plugins that can result in local code execution as a different user. This attack appear to be exploitable via using the --plugin flag without the --plugin-path flag. This vulnerability appears to have been fixed in 1.27.1.
