    It was discovered that the Hotspot component of OpenJDK 11 incorrectly handled certain exceptions with
    specially crafted long messages. An attacker could possibly use this issue to cause a denial of service.
    (CVE-2024-21011)

    It was discovered that OpenJDK 11 incorrectly performed reverse DNS

    query under certain circumstances in the Networking/HTTP client

    component. An attacker could possibly use this issue to obtain sensitive information. (CVE-2024-21012)

    Vladimir Kondratyev discovered that the Hotspot component of OpenJDK 11 incorrectly handled address offset
    calculations in the C1 compiler. An attacker could possibly use this issue to cause a denial of service or
    execute arbitrary code. (CVE-2024-21068)

    Yakov Shafranovich discovered that OpenJDK 11 did not properly manage memory in the Pack200 archive
    format. An attacker could possibly use this issue to cause a denial of service. (CVE-2024-21085)

    It was discovered that the Hotspot component of OpenJDK 11 incorrectly handled array accesses in the C2
    compiler. An attacker could possibly use this issue to cause a denial of service or execute arbitrary
    code. (CVE-2024-21094)
