"The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied
patch available.

  - A flaw was found in glib. An integer overflow during temporary file creation leads to an out-of-bounds
    memory access, allowing an attacker to potentially perform path traversal or access private temporary file
    content by creating symbolic links. This vulnerability allows a local attacker to manipulate file paths
    and access unauthorized data. The core issue stems from insufficient validation of file path lengths
    during temporary file operations. (CVE-2025-7039)

Note that Nessus relies on the presence of the package as reported by the vendor.");
