[Bug 955032] Re: pam environment duplicate path directories since it is called without user_readenv=0
This bug was fixed in the package pam - 1.1.3-8ubuntu1
---
pam (1.1.3-8ubuntu1) raring; urgency=low
* Merge from Debian unstable, remaining changes:
- debian/libpam-modules.postinst: Add PATH to /etc/environment if it's
not present there or in /etc/security/pam_env.conf. (should send to
Debian).
- debian/libpam0g.postinst: only ask questions during update-manager when
there are non-default services running.
- debian/libpam0g.postinst: check if gdm is actually running before
trying to reload it.
- debian/libpam0g.postinst: the init script for 'samba' is now named
'smbd' in Ubuntu, so fix the restart handling.
- Change Vcs-Bzr to point at the Ubuntu branch.
- debian/patches-applied/series: Ubuntu patches are as below ...
- debian/patches-applied/ubuntu-rlimit_nice_correction: Explicitly
initialise RLIMIT_NICE rather than relying on the kernel limits.
- debian/patches-applied/pam_umask_usergroups_from_login.defs.patch:
Deprecate pam_unix' explicit usergroups option and instead read it
from /etc/login.def's USERGROUP_ENAB option if umask is only defined
there. This restores compatibility with the pre-PAM behaviour of login.
- debian/patches-applied/pam_motd-legal-notice: display the contents of
/etc/legal once, then set a flag in the user's homedir to prevent
showing it again.
- debian/update-motd.5, debian/libpam-modules.manpages: add a manpage
for update-motd, with some best practices and notes of explanation.
- debian/patches/update-motd-manpage-ref: add a reference in pam_motd(8)
to update-motd(5)
- debian/local/common-session{,-noninteractive}: Enable pam_umask by
default, now that the umask setting is gone from /etc/profile.
- debian/local/pam-auth-update: Add the new md5sums for pam_umask addition.
- Build-depend on libfl-dev in addition to flex, for cross-building
support.
- Add /usr/local/games to PATH. LP: #110287.
pam (1.1.3-8) unstable; urgency=low
* Confirm NMU for bug #611136; thanks to Michael Gilbert.
- As a side effect, there will no longer be errors from reading the
.pam_environment twice since we are now reading it 0 times.
LP: #955032.
* Adjust the pam_env documentation to match the module behavior resulting
from the previous security upload. Closes: #693995.
* debian/rules: never regenerate manpages at build time; this may cause
build skew that breaks the world in a multiarch context. LP: #1095887.
* debian/patches-applied/glibc-2_16-compilation-fix.patch: fix missing
include causing build failure with eglibc 2.16. Thanks to Daniel
Schepler dschep...@gmail.com. Closes: #693450.
* Ditch autoconf patch in favor of a build-dependency on dh-autoreconf,
which will let us keep up-to-date with newer autotools. In the present
instance, this gets us aarch64 support.
* Install pam_timestamp_check - and while we're at it, move the manpage
to the correct binary package. Closes: #648695.
* Update lintian overrides to suppress some noise about hardening and
manpages.
* Enable audit support, by popular demand. This should have no major
impact unless you're also running auditd; but I reserve the right to
disable this again in the event that this causes a performance hit or
breaks upgrades (since the dependency is pulled into libpam, not just
into pam_tty_audit). Closes: #699159, LP: #937005.
pam (1.1.3-7.1) unstable; urgency=low
* Non-maintainer upload.
* Fix cve-2010-4708: user-configurable .pam_environment allows
administrator-level changes without root access (closes: #611136).

[Bug 955032] Re: pam environment duplicate path directories since it is called without user_readenv=0
Sorry, I was not very explicit about the underlying cause. It appears on the link that I gave (http://superuser.com/questions/135730/why-do-i -get-duplicated-entries-in-my-path), namely in the post (and the answer) gave by Nick Taylor: The problem seems to stem from the fact that pam_env defaults to reading the user ~/.pam_environment every time it is invoked. A lot of login methods (cron, lightdm, lightdm-autologin, login, sshd and su on my machine) invoke pam_env twice: once to read the /etc/environment and ~/.pam_environment files, and once to read the /etc/default/locale file. In neither case is the user_readenv flag set, so pam_env reads, and acts on, your ~/.pam_environment twice. Thank you for taking this issue into consideration. I was wondering if the parameter user_readenv=0 could not be put directly into the /etc/default/locale file. Anyway, thanks again. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/955032 Title: pam environment duplicate path directories since it is called without user_readenv=0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pam/+bug/955032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I had a hard time understanding this at first, until I understood that this was about the fact that pam_env is called *twice* for some services. Yes, we shouldn't be reading the user environment twice; I'm not sure if user_readenv should default to off when 'envfile' is set, or if this should be fixed in the individual packages providing the configs. There's also a related issue that upstream has turned user_readenv off by default in the latest releases due to security concerns, and we should probably follow suit. ** Changed in: pam (Ubuntu) Importance: Undecided = Low ** Changed in: pam (Ubuntu) Status: New = Triaged -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/955032 Title: pam environment duplicate path directories since it is called without user_readenv=0 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/pam/+bug/955032/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
