Critical
| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H |
Name of the Vulnerable Software and Affected Versions
arr crate versions through 2020-08-25
Description
The issue concerns a buffer overflow in
Index and IndexMut implementations. Additionally, there are problems with the implementation of Sync/Send bounds, allowing non-Sync/Send types to be smuggled across thread boundaries. The Array::new from template() function drops uninitialized memory.Recommendations
For versions through 2020-08-25, consider updating to a version released after 2020-08-25 to address the buffer overflow and other security issues.
As a temporary workaround, consider restricting the use of
Index and IndexMut implementations to prevent buffer overflows until a patch is available.
Avoid using the Array::new from template() function until the issue with dropping uninitialized memory is resolved.
At the moment, there is no information about a newer version that contains a fix for this vulnerability.Buffer Overflow
Race Condition
Use of Uninitialized Resource
