NVDhttps://nvd.nist.gov/vuln/detail/CVE-2017-2463
CWEhttps://cwe.mitre.org/data/definitions/416.html

An issue was discovered in certain Apple products. iOS before 10.3 is affected. Safari before 10.1 is affected. iCloud before 6.2 on Windows is affected. iTunes before 12.6 on Windows is affected. tvOS before 10.2 is affected. The issue involves the WebKit component. It allows remote attackers to execute arbitrary code or cause a denial of service (memory corruption and application crash) via a crafted web site.

Weakness

The product reuses or references memory after it has been freed. At some point afterward, the memory may be allocated again and saved in another pointer, while the original pointer references a location somewhere within the new allocation. Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
