WS-2019-0500
Date: June 6, 2019
Attempting to call grow on a spilled SmallVec with a value equal to the current capacity causes it to free the existing data. This performs a double free immediately and may lead to use-after-free on subsequent accesses to the SmallVec contents. An attacker that controls the value passed to grow may exploit this flaw to obtain memory contents or gain remote code execution.
