"The remote Ubuntu 18.04 LTS / 20.04 LTS / 22.04 LTS / 24.04 LTS / 25.04 host has packages installed that are affected by
multiple vulnerabilities as referenced in the USN-7690-1 advisory.

    It was discovered that the 2D component of OpenJDK 17 did not properly manage memory under certain
    circumstances. An attacker could possibly use this issue to cause a denial of service or execute arbitrary
    code. (CVE-2025-30749, CVE-2025-50106)

    VMashroor Hasan Bhuiyan discovered that the JSSE component of OpenJDK 17 did not properly manage TLS 1.3
    handshakes under certain circumstances. An attacker could possibly use this issue to obtain sensitive
    information. (CVE-2025-30754)

    Martin van Wingerden and Violeta Georgieva of Broadcom discovered that the Networking component of OpenJDK
    17 did not properly manage network connections under certain circumstances. An attacker could possibly use
    this issue to obtain sensitive information. (CVE-2025-50059)

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