<!--
There is a use-after-free security vulnerability in WebKit. The vulnerability was confirmed on ASan build of Revision 225572 on OSX.
The PoC is attached.
Preliminary Analysis:
SVGPropertyTearOff keeps a pointer to a SVG property in m_value. When detachWrapper() is called, that pointer gets dereferenced and the value copied. This comment explains when/why this is used
https://github.com/WebKit/webkit/blob/5277f6fb92b0c03958265d24a7692142f7bdeaf8/Source/WebCore/svg/properties/SVGPropertyTearOff.h#L105
SVGPropertyTearOff keeps track of just a single value. In case the SVG property is actually a list of values, the values are stored in a Vector and SVGPropertyTearOff will keep a pointer to somewhere inside the vector's buffer. If a vector gets resized before detachWrapper() is called and the vector's buffer gets realloc()'ed, SVGPropertyTearOff's m_value will point to freed memory.
