RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Description of problem:
There is a bug in Nautilus that makes it possible to disguise a malicious script as an innocent document, like a PDF or ODT, that gets executed when the user opens it.
The upstream nautilus issue [1] has already been resolved, and will be released in nautilus 3.24. But since this is an important security issue, I think this patch should be backported so that it's fixed in older versions of Fedora.
See this blog post [2] for more about how this bug allows attackers to compromise Subgraph OS. Fedora is vulnerable to the same type of attack.

Steps to Reproduce:
Make a file called malware.desktop that has this content:
[Desktop Entry]
Encoding=UTF-8
Name=resume.odt
Exec=gnome-calculator
Terminal=false
Type=Application
Icon=libreoffice-writer.png
Now make malware.desktop executable (chmod 755 malware.desktop). If you open nautilus and browse to the folder that this document is in, it looks like there's a LibreOffice document called "resume.odt". But when you double-click on it, it runs the attackers code. In this case, it opens the calculator.

This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle.
Changing version to '27'.
