OK, I have verified that the trusty-proposed version fixes the reported issue.
The steps ran for verification: 1) Start an ubuntu Trusty container 2) cp /etc/apt/sources.list /etc/apt/sources.list.back 3) Disable the trusty-updates and trusty-security archives in /etc/apt/sources.list 4) sudo apt-get update 5) sudo apt-get install samba winbind libnss-winbind libpam-winbind 6) Set /etc/nsswitch.conf to : passwd: winbind compat 7) Restart the services 7.1) sudo restart smbd 7.2) sudo restart nmbd 7.3) sudo restart winbind 8) cp /etc/apt/sources.list.back /etc/apt/sources.list 9) sudo apt-get update 7) sudo apt-get install samba winbind libnss-winbind libpam-winbind The segmentation fault mentioned before is not experience, Also with the patch applied: root@samba:~# ldd /lib/x86_64-linux-gnu/security/pam_winbind.so linux-vdso.so.1 => (0x00007ffe0bdaf000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fb246748000) libbsd.so.0 => /lib/x86_64-linux-gnu/libbsd.so.0 (0x00007fb246539000) libtalloc.so.2 => /usr/lib/x86_64-linux-gnu/libtalloc.so.2 (0x00007fb24632c000) libpam.so.0 => /lib/x86_64-linux-gnu/libpam.so.0 (0x00007fb24611e000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fb245d59000) /lib64/ld-linux-x86-64.so.2 (0x000055695ab59000) libaudit.so.1 => /lib/x86_64-linux-gnu/libaudit.so.1 (0x00007fb245b34000) libdl.so.2 => /lib/x86_64-linux-gnu/libdl.so.2 (0x00007fb245930000) root@samba:~# ldd /lib/x86_64-linux-gnu/libnss_winbind.so.2 linux-vdso.so.1 => (0x00007fffe9195000) libpthread.so.0 => /lib/x86_64-linux-gnu/libpthread.so.0 (0x00007fd3e84f7000) libc.so.6 => /lib/x86_64-linux-gnu/libc.so.6 (0x00007fd3e8132000) /lib64/ld-linux-x86-64.so.2 (0x0000563f59046000) ** Tags added: verification-done-trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1584485 Title: Upgrading samba to latest security fixes together with winbind in nsswitch.conf can harm entire OS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/samba/+bug/1584485/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
