RUSTSEC-2020-0071: Potential segfault in the time crate
Potential segfault in the time crate
Details | |
---|---|
Package | time |
Version | 0.1.45 |
URL | time-rs/time#293 |
Date | 2020-11-18 |
Patched versions | >=0.2.23 |
Unaffected versions | =0.2.0,=0.2.1,=0.2.2,=0.2.3,=0.2.4,=0.2.5,=0.2.6 |
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.
The affected functions from time 0.2.7 through 0.2.22 are:
time::UtcOffset::local_offset_at
time::UtcOffset::try_local_offset_at
time::UtcOffset::current_local_offset
time::UtcOffset::try_current_local_offset
time::OffsetDateTime::now_local
time::OffsetDateTime::try_now_local
The affected functions in time 0.1 (all versions) are:
at
at_utc
now
Non-Unix targets (including Windows and wasm) are unaffected.
Patches
Pending a proper fix, the internal method that determines the local offset has been modified to always return None
on the affected operating systems. This has the effect of returning an Err
on the try_*
methods and UTC
on the non-try_*
methods.
Users and library authors with time in their dependency tree should perform cargo update
, which will pull in the updated, unaffected code.
Users of time 0.1 do not have a patch and should upgrade to an unaffected version: time 0.2.23 or greater or the 0.3 series.
Workarounds
A possible workaround for crates affected through the transitive dependency in chrono
, is to avoid using the default oldtime
feature dependency of the chrono
crate by disabling its default-features
and manually specifying the required features instead.
Examples:
Cargo.toml
:
chrono = { version = "0.4", default-features = false, features = ["serde"] }
chrono = { version = "0.4.22", default-features = false, features = ["clock"] }
Commandline:
cargo add chrono --no-default-features -F clock

RUSTSEC-2023-0001: reject_remote_clients Configuration corruption
reject_remote_clients Configuration corruption
Details | |
---|---|
Package | tokio |
Version | 1.19.2 |
URL | GHSA-7rrj-xr53-82p7 |
Date | 2023-01-04 |
Patched versions | >=1.18.4, <1.19.0,>=1.20.3, <1.21.0,>=1.23.1 |
Unaffected versions | <1.7.0 |
On Windows, configuring a named pipe server with pipe_mode will force ServerOptions::reject_remote_clients as false
.
This drops any intended explicit configuration for the reject_remote_clients that may have been set as true
previously.
The default setting of reject_remote_clients is normally true
meaning the default is also overridden as false
.
Workarounds
Ensure that pipe_mode is set first after initializing a ServerOptions. For example:
let mut opts = ServerOptions::new();
opts.pipe_mode(PipeMode::Message);
opts.reject_remote_clients(true);
See advisory page for additional details.
