When parsing certain messages, the process aborts with a stack overflow.

I made a reproducer:

prost-stackoverflow-reproducer$ cargo run
     Running `target/debug/prost-stackoverflow-reproducer`
Hello, world!

thread 'main' has overflowed its stack
fatal runtime error: stack overflow
Aborted (core dumped)

Potentially the data requests allocation of a buffer that's larger than the actually available data? (23 KiB input data is not that large...)

(Found through afl.rs)

Wow nice, thanks for the report. Getting a stack trace, if possible, would be super great if you are still looking at this (otherwise no worries, it should be easy to repro thanks to your repo). We have some fuzzers in-tree, but they haven't dug this up. That's something to be investigated as well, or maybe we can just upstream you're test into prost.

I found it, I believe it's this recursive call within skip_field: https://github.com/danburkert/prost/blob/master/src/encoding.rs#L402. It should be straightforward to restructure that as a loop instead of recursion. Interestingly it doesn't manifest in release mode.

Interestingly it doesn't manifest in release mode.

It likely would with longer input.

@dbrgn thanks again for the report, and thorough repro. Fix has been released in 0.6.1; more details are in the release notes: https://github.com/danburkert/prost/releases/tag/v0.6.1. Additionally I filed #270 to track better fuzz testing through afl.

Great, thank you for the very fast response! 🙂

I will also file a RUSTSEC advisory, since this could be used for DoS if untrusted input is fed to the parser.

Note that in absence of stack probes on architectures like ARM, stack overflow is unsound and can result in potential memory corruption (or even RCE), so it's worse than DoS.

Fortunately x86/x86_64 has stack probes.

Oh, that's a good point! I wasn't aware of that.

I'll file a RUSTSEC advisory. In that case, should I put it both in "denial-of-service" and "memory-corruption" categories?

Yup, sounds good.

Are 0.5 versions affected? If so, is it possible to backport the fix?

0.5.x have no stack overflow protections at all, so yes. There will be no backport, as I don't have the resources to maintain backports.

I tried to visit the link listed: https://github.com/danburkert/prost/issues/267 but it was unavailable.
I saw that this is a fork so I found the issue in the original(?) repo: tokio-rs/prost#267, so I propose to change the link (or remove the line).

-   `BufMut::bytes_mut` returns `&mut [MaybeUninit<u8>]` to reflect the unknown
    initialization state ([#&#8203;305](https://github.com/tokio-rs/bytes/issues/305)).

### [`v0.7.0`](https://github.com/tokio-rs/prost/releases/tag/v0.7.0)

[Compare Source](https://github.com/tokio-rs/prost/compare/v0.6.1...v0.7.0)

*PROST!* is a [Protocol Buffers](https://developers.google.com/protocol-buffers/) implementation for the [Rust Language](https://www.rust-lang.org/). `prost` generates simple, idiomatic Rust code from `proto2` and `proto3` files.

`prost` 0.7.0 includes breaking changes:

-   The minimum-supported Rust version (MSRV) is now 1.46.0.
-   The `bytes` public dependency version is now 1.0.
-   The bundled `protoc` version is now 3.14.0.

As well as many new (non-breaking) features and improvements:

-   [@&#8203;hockeybuggy](https://github.com/hockeybuggy) added support for `deprecated` field annotations.
-   [@&#8203;garbageslam](https://github.com/garbageslam) and [@&#8203;dflemstr](https://github.com/dflemstr) added `no_std` support.
-   [@&#8203;joseph-wakeling-frequenz](https://github.com/joseph-wakeling-frequenz) fixed a bug in Timestamp <-> SystemTime conversions.
-   [@&#8203;rolftimmermans](https://github.com/rolftimmermans) added support for generating Rust `bytes::Bytes` fields from protobuf `bytes` fields. When deserializing from a `Bytes` instance, this enables zero-copy deserialization for `bytes` fields!
-   [@&#8203;olix0r](https://github.com/olix0r) bumped the `bytes` dependency to 0.6, which included most of the heavy lifting for the subsequent move to `bytes` 1.0.
-   [@&#8203;danburkert](https://github.com/danburkert) added support for the experimental proto3 optional field presence feature.

and numerous smaller fixes. Many thanks to the generous contributors who have helped out since 0.6.1:

### [`v0.6.1`](https://github.com/tokio-rs/prost/releases/tag/v0.6.1)

[Compare Source](https://github.com/tokio-rs/prost/compare/v0.6.0...v0.6.1)

*PROST!* is a [Protocol Buffers](https://developers.google.com/protocol-buffers/) implementation for the [Rust Language](https://www.rust-lang.org/). `prost` generates simple, idiomatic Rust code from `proto2` and `proto3` files.

`prost` 0.6.1 fixes a bug in which decoding untrusted input could overflow the stack. The bug was reported by [@&#8203;dbrgn](https://github.com/dbrgn) in [#&#8203;267](https://github.com/tokio-rs/prost/issues/267) (with an attached repro!), and fixed by [@&#8203;danburkert](https://github.com/danburkert). The fix extended the same recursion limits introduced in [#&#8203;186](https://github.com/tokio-rs/prost/issues/186) by [@&#8203;nrc](https://github.com/nrc) (released in 0.6.0) to the logic which skips unknown fields during decoding, which became recursive when support was added for decoding groups (also released in 0.6.0). The 0.6.0 release of the `prost` crates has been yanked from crates.io.

Additionally, [@&#8203;koushiro](https://github.com/koushiro) updated the private dependencies of all `prost` crates to the latest versions.

### [`v0.6.0`](https://github.com/tokio-rs/prost/releases/tag/v0.6.0)

[Compare Source](https://github.com/tokio-rs/prost/compare/v0.5.0...v0.6.0)

*PROST!* is a [Protocol Buffers](https://developers.google.com/protocol-buffers/) implementation for the [Rust Language](https://www.rust-lang.org/). `prost` generates simple, idiomatic Rust code from `proto2` and `proto3` files.

`prost` 0.6.0 includes breaking changes:

-   The minimum-supported Rust version (MSRV) is now 1.39.0.
-   The `bytes` public dependency version is now `0.5`.
-   The prost-types `Timestamp` and `Duration` types now impl `TryFrom` for their
    `std::time` equivalents. The old inherent `try_from` methods have been
    removed.
-   Deeply nested messages now fail decoding with an error, instead of potentially
    resulting in a stack overflow. The limit is set to a nesting depth of 100, and
    the limit can be disabled using a new `no-recursion-limit` Cargo feature.

As well as many new (non-breaking) features and improvements:

-   [@&#8203;hanya](https://github.com/hanya) added support for protobuf Group types.
-   [@&#8203;danburkert](https://github.com/danburkert) improved the benchmark suite, including adding support for the
    full set of upstream message encoding and decoding benchmarks.
-   [@&#8203;nrc](https://github.com/nrc) implemented a series of micro-optimizations which result in faster
    message encoding and decoding.
-   [@&#8203;dunmatt](https://github.com/dunmatt) improved the method docs on generated types.
-   [@&#8203;lukaslueg](https://github.com/lukaslueg) removed the dependency on `byteorder`.
-   [@&#8203;parasyte](https://github.com/parasyte) added the `ServiceGenerator::finalize_package`, which is useful for
    advanced service generators.
-   [@&#8203;joelgallant](https://github.com/joelgallant) improved the error message that occurs when attempting to compile
    .proto files without a package specifier.
-   [@&#8203;LucioFranco](https://github.com/LucioFranco) removed the direct dependency of generated types on the `bytes`
    crate, which means applications which use `prost` code generation are no
    longer required to declare a `bytes` dependency.
-   [@&#8203;ErichDonGubler](https://github.com/ErichDonGubler) and [@&#8203;hobofan](https://github.com/hobofan) bumped the `syn`, `quote`, and `proc-macro2` to stable
    versions.
-   [@&#8203;Timmmm](https://github.com/Timmmm) improved `prost-build` so that it no longer writes .rs files when they
    are unchanged, which improves working with tools like `cargo watch` in
    codebases with `prost` code generation.
-   [@&#8203;Hirevo](https://github.com/Hirevo) replaced usage of `failure` with `anyhow`.
-   [@&#8203;danburkert](https://github.com/danburkert) bumped the packaged `protoc` version to 3.11.2.
