  • Binary file formats and network protocols are hard to parse safely: The libpng image decompression library had 24 remotely exploitable vulnerabilities from 2007 to 2013.

Most of these attacks involve memory corruption—therefore, it is easy to assume that solving memory corruption will end all our woes when handling untrusted inputs.
