Description

A specially-crafted file can cause libjxl&amp;#39;s decoder to read pixel data from uninitialized (but allocated) memory.<br /> <br /> This can be done by causing the decoder to reference an outside-image-bound area in a subsequent patches. An incorrect optimization causes the decoder to omit populating those areas.
