An issue was discovered in the stack_dst crate before 0.6.1 for Rust. Because of the push_inner behavior, a double free can occur upon a val.clone() panic.

GHSA-8mjx-h23h-w2pg — Double free in stack_dst

Affected: crates.io: stack_dst

Affected versions of stack_dst used a push_inner function that increased the internal length of the array and then called val.clone(). If the val.clone() call panics, the stack could drop an already dropped element or drop uninitialized memory. This issue was fixed in `2a4d538` by increasing the length of the array after elements are cloned.
