An out of bounds read exists in libjxl. An attacker using a specifically crafted file could cause an out of bounds read in the exif handler. We recommend upgrading to version 0.8.1 or past commit https://github.com/libjxl/libjxl/pull/2101/commits/d95b050c1822a5b1ede9e0dc937e43fca1b10159 https://github.com/libjxl/libjxl/pull/2101/commits/d95b050c1822a5b1ede9e0dc937e43fca1b10159

The remote Ubuntu 24.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in 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)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Debian 12 host has packages installed that are affected by multiple vulnerabilities as referenced in the dsa-5958 advisory.

    Multiple vulnerabilities are discovered in jpeg-xl, the JPEG XL (JXL)     image coding library, including out of bounds read/write and stack based     buffer overflow, which may cause excessive memory usage and denial of     service attacks.

    CVE-2023-0645

        Specifically crafted file could cause an out of bounds read in the exif         handler of libjxl.

    CVE-2023-35790

        Integer underflow in patch decoding code of libjxl.

    CVE-2024-11403

        Out of bounds write in the JPEG decoder used for recompression of JPEG         files.

    CVE-2024-11498

        Specifically crafted file could cause the JPEG XL decoder to use large         amounts of stack space, potentially exhausting the stack.

    For the stable distribution (bookworm), these problems have been fixed in     version 0.7.0-10+deb12u1.

    We recommend that you upgrade your jpeg-xl packages.
