{"id":"USN-8327-1","summary":"openjdk-17 vulnerabilities","details":"Thomas Beckers discovered that the JAXP component of OpenJDK 17 did not\ncorrectly authenticate certain APIs. A remote unauthenticated attacker\ncould possibly use this issue to gain unauthorized access to sensitive\ninformation. (CVE-2026-22016)\n\nIt was discovered that the Networking component of OpenJDK 17 did not\ncorrectly authenticate certain APIs. A remote unauthenticated attacker\ncould possibly use this issue to cause a denial of service.\n(CVE-2026-34282)\n\nIt was discovered that the JSSE component of OpenJDK 17 did not correctly\nauthenticate certain APIs. A remote unauthenticated attacker could possibly\nuse this issue to cause a denial of service. (CVE-2026-22021)\n\nIt was discovered that the JGSS component of OpenJDK 17 did not correctly\nauthenticate certain APIs. A remote attacker could possibly use this issue\nto obtain sensitive information. (CVE-2026-22013)\n\nIt was discovered that the 2D component of OpenJDK 17 did not correctly\nhandle certain integer arithmetic. If a user or automated system were\ntricked into opening a specially crafted file, an attacker could possibly\nuse this issue to leak sensitive information. (CVE-2026-23865)\n\nIt was discovered that the Libraries component of OpenJDK 17 did not\ncorrectly authenticate certain APIs. A remote unauthenticated attacker\ncould possibly use this issue to cause a denial of service.\n(CVE-2026-22018)\n\nKen Pyle discovered that the Security component of OpenJDK 17 did not\ncorrectly authenticate certain APIs. A local attacker could possibly use\nthis issue to leak sensitive information. (CVE-2026-22007, CVE-2026-34268)\n\nIn addition to security fixes, the updated packages contain bug fixes, new\nfeatures, and possibly incompatible changes.\n\nPlease see the following for more
