the USN-7637-1 advisory.

    It was discovered that libjxl did not perform proper bounds checking when parsing Exif tags. An attacker
    could possibly use this issue to cause libjxl to crash, resulting in a denial of service. (CVE-2023-0645)

    It was discovered that libjxl did not perform proper bounds checking

    when decoding patches. An attacker could possibly use this issue to cause libjxl to enter an infinite
    loop, resulting in a denial of

    service. (CVE-2023-35790)

    It was discovered that libjxl did not perform proper bounds checking when performing JPEG recompression.
    An attacker could possibly use this issue to cause libjxl to crash, resulting in a denial of service, or
    possibly execute arbitrary code. (CVE-2024-11403)

    It was discovered that libjxl incorrectly handled parsing certain image files. An attacker could possibly
    use this issue to cause libjxl to

    consume excessive amounts of memory, resulting in a denial of service. (CVE-2024-11498)
