"According to the versions of the glib2 package installed, the EulerOS installation on the remote host is affected by the
following vulnerabilities :

    A flaw was found in glib. Missing validation of offset and count parameters in the
    g_buffered_input_stream_peek() function can lead to an integer overflow during length calculation. When
    specially crafted values are provided, this overflow results in an incorrect size being passed to
    memcpy(), triggering a buffer overflow. This can cause application crashes, leading to a Denial of Service
    (DoS).(CVE-2026-0988)

    A flaw was found in glib. This vulnerability allows a heap buffer overflow and denial-of-service (DoS) via
    an integer overflow in GLib's GIO (GLib Input/Output) escape_byte_string() function when processing
    malicious file or remote filesystem attribute values.(CVE-2025-14512)

    A heap-based buffer overflow problem was found in glib through an incorrect calculation of buffer size in
    the g_escape_uri_string() function. If the string to escape contains a very large number of unacceptable
    characters (which would need escaping), the calculation of the length of the escaped string could
    overflow, leading to a potential write off the end of the newly allocated string.(CVE-2025-13601)

    A flaw was found in GLib (Gnome Lib). This vulnerability allows a remote attacker to cause heap
    corruption, leading to a denial of service or potential code execution via a buffer-underflow in the
    GVariant parser when processing maliciously crafted input strings.(CVE-2025-14087)

Tenable has extracted the preceding description block directly from the EulerOS glib2 security advisory.

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