Advisories for Cargo/Toodee package

An off-by-one error in the DrainCol::drop destructor could cause an unsafe memory copy operation to exceed the bounds of the associated vector. The error was related to the size of the data being copied in one of the ptr::copy invocations inside the destructor. When removing the first column from a TooDee object, the DrainCol return object could cause a heap buffer overflow vulnerability when it is dropped. The issue was …

The space reserved for the new elements was based on the len() returned by the ExactSizeIterator. This could result in elements in the array being freed twice if the iterator panics. Uninitialized or previously freed elements could also be exposed if the len() didn't match the number of elements. These issues were …
