Bug ID: 99251
Summary: Can't apparmor secure libreoffice splash screen
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: LibreOffice
Assignee: libreoffice-bugs@lists.freedesktop.org
Reporter: gquigs+b...@gmail.com
Generate apparmor profiles per /sysui/desktop/share/apparmor.sh script.
Note, how it longer lets LibreOffice startup. If you delete the apparmor
oosplash it works fine.
Even if you give very open permissions:
/** rmw,
/* rmw,
/ rmw,
It still doesn't work.
The apparmor audit logs doesn't say what is failing. It seems with apparmor
enabled the splash screen "forgets" where it is, see strace excerpt:
