{"id":"USN-8341-1","summary":"openjdk-26 vulnerabilities","details":"Thomas Beckers discovered that the JAXP component of OpenJDK 26 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 26 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 26 did not correctly\nauthenticate certain APIs. A remote unauthenticated attacker could\npossibly use this issue to cause a denial of service. (CVE-2026-22021)\n\nIt was discovered that the JGSS component of OpenJDK 26 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 26 did not correctly\nhandle certain integer arithmetic. If a user or automated system were\ntricked into opening a specially crafted file, an attacker could\npossibly use this issue to obtain sensitive information. (CVE-2026-23865)\n\nIt was discovered that the Libraries component of OpenJDK 26 did not\ncorrectly authenticate certain APIs. A remote unauthenticated attacker\ncould possibly use this issue to modify data.
