User interaction is required to exploit this vulnerability in that the target must visit a malicious page or open a malicious file. The specific flaw exists within the library's implementation of the first-letter style in the context of an SVG text element. Upon applying the style to this element, the library will calculate the height for determining the overflow for an inline box. While traversing the elements for the height, the library will utilize data from a non-existent linebox. Successful exploitation will lead to code execution under the context of the application.
