    Yi Yang discovered that the Hotspot component of OpenJDK 17 incorrectly handled array accesses in the C1
    compiler. An attacker could possibly use this issue to cause a denial of service, execute arbitrary code
    or bypass Java sandbox restrictions. (CVE-2024-20918)

    It was discovered that the Hotspot component of OpenJDK 17 did not properly verify bytecode in certain
    situations. An attacker could possibly use this issue to bypass Java sandbox restrictions.
    (CVE-2024-20919)

    It was discovered that the Hotspot component of OpenJDK 17 had an optimization flaw when generating range
    check loop predicates. An attacker could possibly use this issue to cause a denial of service, execute
    arbitrary code or bypass Java sandbox restrictions. (CVE-2024-20921)

    Yakov Shafranovich discovered that OpenJDK 17 incorrectly handled ZIP archives that have file and
    directory entries with the same name. An attacker could possibly use this issue to bypass Java sandbox
    restrictions. (CVE-2024-20932)

    It was discovered that OpenJDK 17 could produce debug logs that contained private keys used for digital
    signatures. An attacker could possibly use this issue to obtain sensitive information. (CVE-2024-20945)

    Hubert Kario discovered that the TLS implementation in OpenJDK 17 had a timing side-channel and
    incorrectly handled RSA padding. A remote attacker could possibly use this issue to recover sensitive
    information. (CVE-2024-20952)
