NVDhttps://nvd.nist.gov/vuln/detail/CVE-2016-5274
CWEhttps://cwe.mitre.org/data/definitions/416.html

Use-after-free vulnerability in the nsFrameManager::CaptureFrameState function in Mozilla Firefox before 49.0, Firefox ESR 45.x before 45.4, and Thunderbird < 45.4 allows remote attackers to execute arbitrary code by leveraging improper interaction between restyling and the Web Animations model implementation.

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
