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

The remote host is running a version of macOS / Mac OS X that is 11.x prior to 11.3 Big Sur. It is, therefore, affected by multiple vulnerabilities including the following:

  - A memory corruption issue which could allow an application restricted memory read access (CVE-2021-1808).

  - A memory corruption issue which could allow an application to cause unexpected system termination or to     write kernel memory (CVE-2021-1828).

  - An out-of-bounds wirte issue which could allow a malicious application to execute arbitrary code with     kernel privileges (CVE-2021-1834).

Note that Nessus has not tested for this issue but has instead relied only on the operating system's self-reported version number.

The version of Apple iTunes installed on the remote Windows host is prior to 12.11.3. It is, therefore, affected by multiple vulnerabilities as referenced in the HT212319 advisory.

  - In FreeBSD 12.1-STABLE before r364644, 11.4-STABLE before r364651, 12.1-RELEASE before p9, 11.4-RELEASE     before p3, and 11.3-RELEASE before p13, improper handling in the kernel causes a use-after-free bug by     sending large user messages from multiple threads on the same SCTP socket. The use-after-free situation     may result in unintended kernel behaviour including a kernel panic. (CVE-2020-7463)

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

The remote SUSE Linux SLED15 / SLED_SAP15 / SLES15 / SLES_SAP15 host has packages installed that are affected by multiple vulnerabilities as referenced in the SUSE-SU-2022:0182-1 advisory.

The remote AlmaLinux 8 host has packages installed that are affected by multiple vulnerabilities as referenced in the ALSA-2021:1586 advisory.

  - 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)

  - A type confusion issue was addressed with improved memory handling. This issue is fixed in Safari 14.0.

  - gdm3 versions before 3.36.2 or 3.38.2 would start gnome-initial-setup if gdm3 can't contact the     accountservice service via dbus in a timely manner; on Ubuntu (and potentially derivatives) this could be     be chained with an additional issue that could allow a local user to create a new privileged account.
