RUSTSEC-2020-0072
No affected components available
GenericMutexGuard<T> was given the Sync auto trait as long as T is Send
due to its contained members. However, since the guard is supposed to represent
an acquired lock and allows concurrent access to the underlying data from
different threads, it should only be Sync when the underlying data is.
This is a soundness issue and allows data races, potentially leading to crashes and segfaults from safe Rust code.
The flaw was corrected by adding a T: Send + Sync bound for
GenericMutexGuard's Sync trait.
This bug is similar to one in
std::sync::Mutex.
The vulnerability requires local access to the device to be exploited. It is easy for an attacker to exploit this vulnerability. An attacker needs basic access or low-level privileges. No user interaction is needed for the attacker to exploit this vulnerability. The impact is confined to the system where the vulnerability exists. There is a high impact on the availability of the system.
Exploitation attempts have been detected. Elevated vigilance and prompt remediation are advised.
Probability that this vulnerability will be exploited in the wild within the next 30 days.
