Affected packages

• crates.io memoffset: < 0.5.0 → fixed in 0.5.0

Description

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.
