"summary": "openjdk-21 vulnerabilities",
"details": "Yi Yang discovered that the Hotspot component of OpenJDK 21 incorrectly\nhandled array accesses in the C1 compiler. An attacker could possibly\nuse this issue to cause a denial of service, execute arbitrary code or\nbypass Java sandbox restrictions. (CVE-2024-20918)\n\nIt was discovered that the Hotspot component of OpenJDK 21 did not\nproperly verify bytecode in certain situations. 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 21 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\nIt was discovered that OpenJDK 21 could produce debug logs that contained\nprivate keys used for digital signatures. An attacker could possibly use\nthis issue to obtain sensitive information. (CVE-2024-20945)\n\nHubert Kario discovered that the TLS implementation in OpenJDK 21 had a\ntiming side-channel and incorrectly handled RSA padding. A remote attacker\ncould possibly use this issue to recover sensitive information.\n(CVE-2024-20952)\n",
