RUSTSEC-2020-0073
No affected components available
A mutable reference to a struct was constructed by dereferencing a pointer
obtained from slice::as_ptr. Instead, slice::as_mut_ptr should have been
called on the mutable slice argument. The former performs an implicit reborrow
as an immutable shared reference which does not allow writing through the
derived pointer.
There is no evidence for miscompilation, exploitable or otherwise, caused by this bug. Further investigation on Zulip suggests that the unoptimized generated LLVM IR does not contain any UB itself, effectively mitigating further effects.
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.
The exploit probability is very low. The vulnerability is unlikely to be exploited in the next 30 days.
We did not find any exploit available. Neither in GitHub repositories nor in the Exploit-Database.
