Summary
blurhash panics on parsing crafted inputs
Details

Impact

The blurhash parsing code may panic due to multiple panic-guarded out-of-bounds accesses on untrusted input.

In a typical deployment, this may get triggered by feeding a maliciously crafted blurhashes over the network. These may include: - UTF-8 compliant strings containing multi-byte UTF-8 characters

Patches

The patches will be released under version 0.2.0, which requires user intervention because of slight API churn.
