Affected packages
• crates.io arenavec: <= 0.1.1 (no fix yet)
Description
Affected versions of this crate did not guard against potential panics that may happen from user-provided functions T::default() and T::drop().
Panic within T::default() leads to dropping uninitialized T, when it is invoked from common::Slice::::new(). Panic within T::drop() leads to double drop of T, when it is invoked either from common::SliceVec::::resize_with() or common::SliceVec::::resize()
Either case causes memory corruption in the heap memory.
