CVE-2023-42447

blurhash-rs is a pure Rust implementation of Blurhash, software for encoding images into ASCII strings that can be turned into a gradient of colors representing the original image. In version 0.1.1, 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. A patch is available in version 0.2.0, which requires user intervention because of slight API churn. No known workarounds are available.

blurhash-rs es una implementación pura de Blurhash en Rust, un software para codificar imágenes en cadenas ASCII que se pueden convertir en un degradado de colores que representan la imagen original. En la versión 0.1.1, el código de análisis de Blurhash puede entrar en pánico debido a múltiples accesos fuera de límites protegidos contra pánico en entradas que no son de confianza. En una implementación típica, esto puede desencadenarse al alimentar un blurhashes creado con fines malintencionados a través de la red. Estos pueden incluir cadenas compatibles con UTF-8 que contienen caracteres UTF-8 de varios bytes. Hay un parche disponible en la versión 0.2.0, que requiere la intervención del usuario debido a una ligera rotación de API. No hay workarounds conocidos disponibles.
