Description

Use-after-free vulnerability in the mozilla::DOMSVGLength::GetTearOff function in Mozilla Firefox before 32.0, Firefox ESR 31.x before 31.1, and Thunderbird 31.x before 31.1 allows remote attackers to execute arbitrary code or cause a denial of service (heap memory corruption) via an SVG animation with DOM interaction that triggers incorrect cycle collection.

• CWE-416Use After FreeThe 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 Any operations using the original pointer are no longer valid because the memory "belongs" to the code that operates on the new pointer.
