Package: apparmor Version: 4.1.0-1 Severity: normal X-Debbugs-Cc: [email protected]
Dear Maintainer, While testing the “Sign Digitally” feature in GNOME Papers, I found that the signing process fails due to AppArmor blocking access to several paths required by NSS and by smartcard middleware. I reproduced the same issue on Ubuntu as well and documented it here: https://bugs.launchpad.net/ubuntu/+source/apparmor/+bug/2106133 The audit log shows consistent AppArmor denials such as: - ~/.pki/nssdb/cert9.db (file_lock) - ~/.mozilla/firefox/*/cert9.db (read) - /run/pcscd/pcscd.comm (connect) - /sys/devices/... (open) Because of these denials, Papers cannot initialize NSS and shows errors such as: “NSS_Init failed: security library: bad database.” After testing, I confirmed that extending the AppArmor profile resolves the issue and restores the digital-signature functionality. Adding the following rules to `/etc/apparmor.d/usr.bin.papers` fixes the problem: owner @{HOME}/.pki/** lrk, /sys/devices/** r, /run/pcscd/pcscd.comm rw, Since this behavior is caused by the AppArmor policy rather than by Papers itself, it seems appropriate for the issue to be handled within the `apparmor` package. If possible, please consider adjusting the AppArmor profile in Debian so that GNOME Papers can access the necessary NSS and smartcard paths by default. Best regards, Cristiano Fraga G.
