CWEhttps://cwe.mitre.org/data/definitions/416.html

Use-after-free vulnerability in the nsNodeUtils::NativeAnonymousChildListChange function in Mozilla Firefox before 48.0 and Firefox ESR 45.x before 45.3 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via an SVG element that is mishandled during effect application.

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
