An attacker could\npossibly use this issue to bypass Java sandbox restrictions.\n(CVE-2024-20919)\n\nIt was discovered that the Hotspot component of OpenJDK 11 had an\noptimization flaw when generating range check loop predicates. An attacker\ncould possibly use this issue to cause a denial of service, execute\narbitrary code or bypass Java sandbox restrictions. (CVE-2024-20921)\n\nValentin Eudeline discovered that OpenJDK 11 incorrectly handled certain\noptions in the Nashorn JavaScript subcomponent. An attacker could\npossibly use this issue to execute arbitrary code. (CVE-2024-20926)\n\nIt was discovered that OpenJDK 11 could produce debug logs that contained\nprivate keys used for digital signatures. An attacker could possibly use\nthis issue to obtain sensitive information.
