Description
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.
