RUSTSEC-2020-0159: Potential segfault in `localtime_r` invocations

Potential segfault in localtime_r invocations

Details
Package	chrono
Version	0.4.19
URL	chronotope/chrono#499
Date	2020-11-10

Impact

Unix-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.

Workarounds

No workarounds are known.

RUSTSEC-2022-0004: Stack overflow in rustc_serialize when parsing deeply nested JSON

Stack overflow in rustc_serialize when parsing deeply nested JSON

Details
Package	rustc-serialize
Version	0.3.24
Date	2022-01-01

When parsing JSON using json::Json::from_str, there is no limit to the depth of the stack, therefore deeply nested objects can cause a stack overflow, which aborts the process.

Example code that triggers the vulnerability is

fn main() {
    let _ = rustc_serialize::json::Json::from_str(&"[0,[".repeat(10000));
}

serde is recommended as a replacement to rustc_serialize.

RUSTSEC-2019-0031: spin is no longer actively maintained

spin is no longer actively maintained

Details
Status	unmaintained
Package	spin
Version	0.5.2

The author of the spin crate does not have time or interest to maintain it.

Consider the following alternatives (both of which support no_std):

• conquer-once
• lock_api (a subproject of parking_lot)
  • spinning_top spinlock crate built on lock_api

RUSTSEC-2021-0124: Data race when sending and receiving after closing a `oneshot` channel

Data race when sending and receiving after closing a oneshot channel

Details
Package	tokio
Version	0.2.25
URL	tokio-rs/tokio#4225
Date	2021-11-16
Patched versions	>=1.8.4, <1.9.0,>=1.13.1
Unaffected versions	<0.1.14

If 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.
