| Vector | AV:N/AC:L/PR:N/UI:N/S:U/C:N/I:N/A:H |
Name of the Vulnerable Software and Affected Versions
sized-chunks crate versions through 0.6.2
Description
The issue concerns memory safety in the sized-chunks crate for Rust. Specifically, in the Chunk implementation, the array size is not checked when constructed with
From<InlineArray<A, T>>, unit(), or pair(). Additionally, the Clone and insert from functions are not panic-safe, which can cause memory safety issues if an iterator panics. In the InlineArray implementation, unaligned references may be generated for types with large alignment requirements.Recommendations
For sized-chunks crate versions through 0.6.2, consider updating to a version that addresses these memory safety issues. As a temporary workaround, avoid using the
Clone and insert from functions with potentially panicking iterators, and refrain from constructing Chunks with unit(), pair(), or From<InlineArray<A, T>> to minimize the risk of exploitation. Restrict the use of InlineArray for types with large alignment requirements until a fix is available. At the moment, there is no information about a newer version that contains a fix for this vulnerability.Exploit
