+# Heap Buffer Overflow in the DrainCol Destructor
+
+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 fixed in commit `e6e16d5` by reducing the copied size by one.
