    It was discovered that the Hotspot component of OpenJDK 8 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 8 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 8 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)

    Yakov Shafranovich discovered that the Concurrency component of OpenJDK 8 incorrectly performed header
    validation in the Pack200 archive format. An attacker could possibly use this issue to cause a denial of
    service. (CVE-2024-21144)

    Sergey Bylokhov discovered that OpenJDK 8 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 8 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)
