Machine-written summary

Summary written by Claude Haiku from the source advisory. Not reviewed by a person.

The dbn crate, versions before 0.22.1, has a heap buffer overflow in its c_chars_to_str function. If the input character array lacks a null terminator, the function reads past the end of the buffer, which can expose data or corrupt memory. The source does not state what input or attacker access is required to reach this path. Upgrade to dbn 0.22.1 or later.
