Exposure of uninitialized memory in memoffset

Published August 25, 2021Updated November 8, 2023Source: osv

Summary

Affected versions of this crate caused traps and/or memory unsafety by zero-initializing references. They also could lead to uninitialized memory being dropped if the field for which the offset is requested was behind a deref coercion, and that deref coercion caused a panic. The flaw was corrected by using MaybeUninit.
