CVE-2019-15553

An issue was discovered in the memoffset crate before 0.5.0 for Rust. offset_of and span_of can cause exposure of uninitialized memory.

An issue was discovered in the memoffset crate before 0.5.0 for Rust. offset_of and span_of can cause exposure of uninitialized memory.

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`.
