Vulnerability Title
libjxl: Uninitialized memory read in decoder due to incorrect optimization in patch handling
Source: CVE Program / CVE List V5
Vulnerability Description
A specially-crafted file can cause libjxl's decoder to read pixel data from uninitialized (but allocated) memory. 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.
