The version of glib2 installed on the remote host is prior to 2.36.3-5.23. It is, therefore, affected by multiple vulnerabilities as referenced in the ALAS-2023-1742 advisory.

    In GNOME GLib 2.56.1, g_markup_parse_context_end_parse() in gmarkup.c has a NULL pointer dereference.
    (CVE-2018-16428)

    GNOME GLib 2.56.1 has an out-of-bounds read vulnerability in g_markup_parse_context_parse() in gmarkup.c,     related to utf8_str(). (CVE-2018-16429)

    The keyfile settings backend in GNOME GLib (aka glib2.0) before 2.60.0 creates directories using     g_file_make_directory_with_parents (kfsb->dir, NULL, NULL) and files using g_file_replace_contents     (kfsb->file, contents, length, NULL, FALSE, G_FILE_CREATE_REPLACE_DESTINATION, NULL, NULL, NULL).
    Consequently, it does not properly restrict directory (and file) permissions. Instead, for directories,     0777 permissions are used; for files, default file permissions are used. This is similar to     CVE-2019-12450. (CVE-2019-13012)

    An issue was discovered in GNOME GLib before 2.66.8. When g_file_replace() is used with     G_FILE_CREATE_REPLACE_DESTINATION to replace a path that is a dangling symlink, it incorrectly also     creates the target of the symlink as an empty file, which could conceivably have security relevance if the     symlink is attacker-controlled. (If the path is a symlink to a file that already exists, then the contents     of that file correctly remain unchanged.) (CVE-2021-28153)

    A flaw was found in glib before version 2.63.6. Due to random charset alias, pkexec can leak content from     files owned by privileged users to unprivileged ones under the right condition. (CVE-2021-3800)

    The upstream bug report describes this issue as follows:

    A vulnerability was found in GLib2.0, where DoS caused by handling a malicious text-form variant which is     structured to cause looping superlinear to its text size. Applications are at risk if they parse untrusted     text-form variants. (CVE-2023-24593)

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

The remote Redhat Enterprise Linux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2021:1586 advisory.

    GNOME is the default desktop environment of Red Hat Enterprise Linux.

    The following packages have been upgraded to a later upstream version: accountsservice (0.6.55),     webkit2gtk3 (2.30.4). (BZ#1846376, BZ#1883304)

    Security Fix(es):

    * webkitgtk: type confusion may lead to arbitrary code execution (CVE-2020-9948)

    * webkitgtk: use-after-free may lead to arbitrary code execution (CVE-2020-9951)

    * webkitgtk: out-of-bounds write may lead to code execution (CVE-2020-9983)

    * webkitgtk: use-after-free may lead to arbitrary code execution (CVE-2020-13543)

    * webkitgtk: use-after-free may lead to arbitrary code execution (CVE-2020-13584)

    * glib2: insecure permissions for files and directories (CVE-2019-13012)
