"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 the GIF parser of GdkPixbuf's LZW decoder. When an invalid symbol is encountered
    during decompression, the decoder sets the reported output size to the full buffer length rather than the
    actual number of written bytes. This logic error results in uninitialized sections of the buffer being
    included in the output, potentially leaking arbitrary memory contents in the processed image.
    (CVE-2025-6199)

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