The remote Ubuntu 18.04 LTS host has packages installed that are affected by a vulnerability as referenced in the USN-3994-1 advisory.

    It was discovered that gnome-desktop incorrectly confined thumbnailers. If a user were tricked into     downloading a malicious image file, a remote attacker could possibly combine this issue with another     vulnerability to escape the sandbox and execute arbitrary code.

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

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

gnome-desktop 3.30.2.3 release, fixing thumbnailer sandbox escape, CVE-2019-11460

Note that Tenable Network Security has extracted the preceding description block directly from the Fedora update system website.
Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.

The remote openSUSE 15 host has packages installed that are affected by a vulnerability as referenced in the SUSE- SU-2022:3837-1 advisory.

  - An issue was discovered in GNOME gnome-desktop 3.26, 3.28, and 3.30 prior to 3.30.2.2, and 3.32 prior to     3.32.1.1. A compromised thumbnailer may escape the bubblewrap sandbox used to confine thumbnailers by     using the TIOCSTI ioctl to push characters into the input buffer of the thumbnailer's controlling     terminal, allowing an attacker to escape the sandbox if the thumbnailer has a controlling terminal. This     is due to improper filtering of the TIOCSTI ioctl on 64-bit systems, similar to CVE-2019-10063.
    (CVE-2019-11460)
