description |
[Impact]
* With apparmor enabled (and usr.bin.firefox in enforce mode) there is a crash happening every time right after launching Firefox.
[Test Plan]
* sudo aa-enforce /etc/apparmor.d/usr.bin.firefox
* launch Firefox
* See a similar segfault reported in the syslog:
Jun 10 17:25:40 ubuntu kernel: [ 86.775837] firefox[1765]: segfault at 0 ip 00007f724dd06384 sp 00007fffa7aec450 error 6 in libxul.so[7f724a483000+53b2000]

[Where problems could occur]
The fix adds additional paths to firefox apparmor profile (e.g. affecting /sys/devices/pci* and RealtimeKit1). When using deb version of firefox the browser may chose a different code path to execute than before, so it may affect hw acceleration (the sysfs paths were used by libxul) and audio.
Maybe rendering artifacts and audio sync issues in videos.
