{"id":"USN-8002-1","summary":"openjdk-21 vulnerabilities","details":"It was discovered that the RMI component of OpenJDK 21 would establish\nRMI TCP endpoint connections to a remote host without setting an\nendpoint identification algorithm. An unauthenticated remote attacker\ncould possibly use this issue to steal sensitive information.\n(CVE-2026-21925)\n\nMingijung discovered that the AWT and JavaFX componenets of OpenJDK 21\ncould run programs if Desktop.browse() was supplied a filename as a\nURI. An unauthenticated remote attacker could possibly use this issue\nto execute arbitrary code. (CVE-2026-21932)\n\nZhihui Chen discovered that the Networking component of OpenJDK 21\nwas suceptible to a CRLF injection vulnerability via the HttpServer\nclass. An unauthenticated remote attacker could possibly use this\nissue to modify files or leak sensitive information. (CVE-2026-21933)\n\nIreneusz Pastusiak discovered that the Security component of OpenJDK 21\nfailed to verify provided URIs point to a legitimate source when\nAIA is enabled. An unauthenticated remote attacker could possibly\nuse this issue to redirect users to malicious hosts.\n(CVE-2026-21945)\n\nIn addition to security fixes, the updated packages contain bug fixes,\nnew features, and possibly incompatible changes.\n\nPlease see the following for more
