Package: thunderbird Version: 1:52.3.0-4~deb8u2 Severity: normal Tags: upstream
Dear Maintainer, /etc/apparmor.d/usr.bin.thunderbird has these lines: owner /tmp/** m, owner /var/tmp/** m, Is this really necesarry? If Thunderbir actually tries to mmap files with executable flags, I believe it should be reported as a bug upstream. >From AppArmor wiki [0]: ``` Short form permissions map to m - mmap_x, mprot_wx mmap_x - mmap a file executable mprot_wx - allow transitioning an mmap from w to x, (this sticks for the lifetime of the mmap even if w is removed before trying to apply x ``` I will try to use Thunderbird profile with these lines commented out, I'll see if DENIES appear. By the way, I see same lines on usr.lib.firefox.firefox, maybe it's just old bug and blind copy-paste?
