Overview
Affected versions of this package are vulnerable to Integer Overflow or Wraparound via the SpriteFont file loading process. An attacker can execute arbitrary code by providing a specially crafted .spritefont file that triggers a 32-bit integer overflow during multiplication. This is only exploitable if the application is built for x86 or ARM architectures and processes untrusted or user-supplied .spritefont files.
Workaround
This vulnerability can be mitigated by ensuring that only trusted .spritefont files are used and not accepting user-provided or network-downloaded files.
