Description

Affected versions contain multiple safe APIs that can trigger undefined behavior:

  • Array<T>::index can perform an out-of-bounds read.
  • String::get_length can perform an out-of-bounds read.
  • String::append_character can perform an invalid write.
  • String::to_c_string can perform an out-of-bounds write.

These issues were reproduced against scaly 0.0.37 under Miri. The crate is unmaintained.
