   Hi,   
      
   The following vulnerability was published for jpeg-xl.   
      
   CVE-2025-12474[0]:   
   | 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.
