"The remote Ubuntu 20.04 LTS / 22.04 LTS / 24.04 LTS host has packages installed that are affected by multiple
vulnerabilities as referenced in the USN-6931-1 advisory.

    It was discovered that the Hotspot component of OpenJDK 17 was not properly performing bounds when
    handling certain UTF-8 strings, which could lead to a buffer overflow. An attacker could possibly use this
    issue to cause a

    denial of service or execute arbitrary code. (CVE-2024-21131)

    It was discovered that the Hotspot component of OpenJDK 17 could be made to run into an infinite loop. If
    an automated system were tricked into processing excessively large symbols, an attacker could possibly use
    this issue to cause a denial of service. (CVE-2024-21138)

    It was discovered that the Hotspot component of OpenJDK 17 did not

    properly perform range check elimination. An attacker could possibly use

    this issue to cause a denial of service, execute arbitrary code or bypass Java sandbox restrictions.
    (CVE-2024-21140)

    Sergey Bylokhov discovered that OpenJDK 17 did not properly manage memory when handling 2D images. An
    attacker could possibly use this issue to obtain sensitive information. (CVE-2024-21145)

    It was discovered that the Hotspot component of OpenJDK 17 incorrectly handled memory when performing
    range check elimination under certain circumstances. An attacker could possibly use this issue to cause a

    denial of service, execute arbitrary code or bypass Java sandbox

    restrictions. (CVE-2024-21147)
