Machine-written summary
Summary written by Claude Haiku from the source advisory. Not reviewed by a person.
Versions 0.20.0 up to but not including 0.25.0 of the wasapi crate are affected. In these versions, the WaveFormat::parse function can read 22 bytes past the end of a WAVEFORMATEX header when the header is a WAVE_FORMAT_EXTENSIBLE format with cbSize of at least 22, and this can be reached from safe code, such as by copying a header out of a WASAPI format pointer and passing a reference to it. Upgrade to wasapi 0.25.0 or later. Code that cannot upgrade can use WaveFormat::parse_from_blob_bytes, available since 0.23.0, which checks the slice length against cbSize.
