chrono: Potential segfault in `localtime_r` invocationsUnix-like operating systems may segfault due to dereferencing a dangling pointer in specific circumstances. This requires an environment variable to be set in a different thread than the affected functions. This may occur without the user's knowledge, notably in a third-party library.
No workarounds are known.
tokio: Data race when sending and receiving after closing a `oneshot` channelIf a tokio::sync::oneshot channel is closed (via the
oneshot::Receiver::close method), a data race may occur if the
oneshot::Sender::send method is called while the corresponding
oneshot::Receiver is awaited or calling try_recv.
When these methods are called concurrently on a closed channel, the two halves of the channel can concurrently access a shared memory location, resulting in a data race. This has been observed to cause memory corruption.
Note that the race only occurs when both halves of the channel are used
after the Receiver half has called close. Code where close is not used, or where the
Receiver is not awaited and try_recv is not called after calling close,
is not affected.
See tokio#4225 for more details.
websocket: Unbounded memory allocation based on untrusted lengthUntrusted websocket connections can cause an out-of-memory (OOM) process abort in a client or a server.
The root cause of the issue is during dataframe parsing.
Affected versions would allocate a buffer based on the declared dataframe size, which may come from an untrusted source.
When Vec::with_capacity fails to allocate, the default Rust allocator will abort the current process, killing all threads. This affects only sync (non-Tokio) implementation. Async version also does not limit memory, but does not use with_capacity, so DoS can happen only when bytes for oversized dataframe or message actually got delivered by the attacker.
This is a security concern for you, if
The crashes are fixed in version 0.26.5 by imposing default dataframe size limits. Affected users are advised to update to this version.
Note that default memory limits are rather large (100MB dataframes and 200 MB messages), so they can still cause DoS in some environments (i.e. 32-bit). New API has been added to fine tune those limits for specific applications.
This issue was reported by Evan Richter at ForAllSecure and found with Mayhem and Cargo Fuzz.
snow: Unauthenticated Nonce Increment in snowThere was a logic bug where unauthenticated payloads could still cause a nonce increment in snow's internal state. For an attacker with privileges to inject packets into the channel over which the Noise session operates, this could allow a denial-of-service attack which could prevent message delivery by sending garbage data.
Note that this only affects those who are using the stateful TransportState, not those using StatelessTransportState.
This has been patched in version 0.9.5, and all users are recommended to update.
