"According to the versions of the gdk-pixbuf2 packages installed, the EulerOS installation on the remote host is affected
by the following vulnerabilities :

    A flaw was found in the GIF parser of GdkPixbufs 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)

    No description is available for this CVE.(CVE-2025-7345)

Tenable has extracted the preceding description block directly from the EulerOS gdk-pixbuf2 security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version
number.");
