The subtraction of one pointer from another in order to determine size is dependant on the assumption that both pointers exist in the same memory chunk. There is the potential for arbitrary code execution with privileges of the vulnerable program. The use of tools to prevent these errors should be used. It can be exacerbated by lack of or misuse of mitigating technologies. The risk of an exploit is high. The vulnerability has a long exposure period. The potential for an exploit of this vulnerability is very low. The most likely risk is that an exploit could be triggered by this vulnerability.”]
