Description Oliver Haessler 2019-03-26 09:21:00 UTC
Description of problem:
When opening a PDF or a folder with PDFs, the below selinux error pops up.

Version-Release number of selected component (if applicable):
selinux-policy-3.13.1-229.el7_6.9.noarch


*****  Plugin catchall (100. confidence) suggests **************************

If you believe that evince-thumbnailer should be allowed nnp_transition
nosuid_transition access on processes labeled thumb_t by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# ausearch -c 'evince-thumbnai' --raw | audit2allow -M my-evincethumbnai
# semodule -i my-evincethumbnai.pp
