VULNERABILITY DETAILS |
The specific flaw exists within how the application parses font names embedded within an atom. When parsing the font name, the application will treat a length from the file as a signed value when copying font data into a buffer. Due to an unsigned promotion, this can be used to write outside the bounds of a buffer which can lead to code execution under the context of the application. |
