    It was discovered that libsoup could be made to read out of bounds. An attacker could possibly use this
    issue to cause applications using libsoup to crash, resulting in a denial of service. (CVE-2025-2784,

    It was discovered that libsoup could be made to dereference invalid memory. An attacker could possibly use
    this issue to cause applications using libsoup to crash, resulting in a denial of service.
