Vulnerabilities

libjxl before 0.12 contains an integer underflow vulnerability in the container box parser that allows remote attackers to inject arbitrary metadata by exploiting 64-bit box size truncation to size_t on 32-bit platforms.

A specially-crafted file can cause libjxl's decoder to read pixel data from uninitialized (but allocated) memory.
