Original NVD Description

The SVG implementation in Mozilla Firefox 8.0, Thunderbird 8.0, and SeaMonkey 2.5 does not properly interact with DOMAttrModified event handlers, which allows remote attackers to cause a denial of service (out-of-bounds memory access) or possibly have unspecified other impact via vectors involving removal of SVG elements.
