affected by multiple vulnerabilities as referenced in the USN-7883-1 advisory.

    Jinfeng Guo discovered that the Security component of OpenJDK 17 did not correctly handle certain
    representations of encoded strings. An unauthenticated remote attacker could possibly use this issue to
    modify files or leak sensitive information. (CVE-2025-53057)

    Darius Bohni discovered that the JAXP component of OpenJDK 17 was vulnerable to a XML External Entity
    (XEE) attack. An unauthenticated remote attacker could possibly use this issue to modify files or leak
    sensitive information. (CVE-2025-53066)

    In addition to security fixes, the updated packages contain bug fixes, new features, and possibly
    incompatible changes.
