** Summary changed: - Apparmor profile prevents Tor Browser from loading libstdc++.so.6 since Tor Browser 10.0 was released + [SRU] Apparmor profile prevents Tor Browser from loading libstdc++.so.6 since Tor Browser 10.0 was released
** Description changed: + [Impact] + The AppArmor profile for Tor Browser prevents access to libstdc libraries. This prevents Tor Browser from starting. + + [Test Case] + (1) Install torbrowser-launcher. + (2) Let it download/update. + (3) Program will fail to start when launched with error in attempting to mem-map libstdc libraries. + + [Regression Potential] + The regression potential for the fix for this is near-zero. It simply alters the apparmor profile to permit mem-mapping of libstdc. + + + [Original Bug Description] + The AppArmor profile torbrowser.Browser.firefox prevents Tor Browser from loading libstdc++.so.6 on Ubuntu 20.04. This results in Tor Browser failing to start since 10.0 release with the following error being printed on stdout: ./firefox.real: error while loading shared libraries: libstdc++.so.6: failed to map segment from shared object And the following message in the audit logs: AVC apparmor="DENIED" operation="file_mmap" profile="torbrowser_firefox" name="/home/<user>/.local/share/torbrowser/tbb/x86_64/tor-browser_en- US/Browser/TorBrowser/Tor/libstdc++/libstdc++.so.6" pid=3883 comm="firefox.real" requested_mask="m" denied_mask="m" fsuid=1000 ouid=1000 This patch from Debian fixes the issue: https://salsa.debian.org/pkg- privacy-team/torbrowser- launcher/-/commit/87859bce5779f89b37c4e4be334f7e1670b0a9f3 It is already fixed in Groovy. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1897302 Title: [SRU] Apparmor profile prevents Tor Browser from loading libstdc++.so.6 since Tor Browser 10.0 was released To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/torbrowser-launcher/+bug/1897302/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
