NVDhttps://nvd.nist.gov/vuln/detail/CVE-2012-3968
CWEhttps://cwe.mitre.org/data/definitions/416.html

Use-after-free vulnerability in the WebGL implementation in Mozilla Firefox before 15.0, Firefox ESR 10.x before 10.0.7, Thunderbird before 15.0, Thunderbird ESR 10.x before 10.0.7, and SeaMonkey before 2.12 allows remote attackers to execute arbitrary code via vectors related to deletion of a fragment shader by its accessor.

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 Any operations using the original pointer are no longer valid because the memory “belongs” to the code that operates on the new pointer.
