Bug description:
  [Impact]

   * Some PAM modules produce output of more than 1 line (e.g.
  PAM_TEXT_INFO may contain newlines in the message content). Polkit
  authentication agent is prepared to receive only single-line messages
  so it treats each line as a separate message. It fails to recognize
  the type of message for all of them except the first - hence failed
  authorization even if it was successful on the PAM-level.

   * The PAM specification does not require the modules to send only
  single-line messages. Thus, polkit needs to be fixed.

  * The helper component should escape (g_strescape) all messages before
  sending it up to the authentication agent. This way everything will be
  read as a single line and then unescaped to restore it's formatting
  with no changes required in PAM modules.

  [Test Case]

   * Use a pam module that returns a multi-line PAM_TEXT_INFO message on
  successful authentication (may require to artificially modify a pam
  module).

   * Perform a polkit authorization with e.g. pkexec ls

   * Correct authorization should end with a failure with an
  unrecognized PAM message

  [Regression Potential]

   * Fix makes advantage of the fact that polkit authentication agent
  already un-escapess (g_strcompress) all input from the helper
  component.

  * Fix is a backport of an upstream change.

  [Other Info]

   * Original bug description:

  There is an error observed when Ubuntu is configured to perform
  authentication via pam_vas (Vintela Authentication Services by Dell)
  in a disconnected mode (using cached authentication).

  Steps to reproduce:
  1. Configure pam_vas client authenticating to a remote server.
  2. Perform authentication to cache the credentials.
  3. Disconnect from the network where the server is reachable (to force using 
cached information).
  4. Perform an action requiring polkit authentication.

  Expected result:
  Authentication succeeds accompanied by the following message "You have logged 
in using cached account information.  Some network services will be 
unavailable".

  Actual result:
  Authentication fails accompanied by the following message "You have logged in 
using cached account information.  Some network services will be unavailable".

  Probable cause:
  The PolkitAgentSession part of polkit is designed to interpret only 1-line 
output, while interaction with pam_vas in the above scenario triggers helper to 
produce the following 2-line output:
  PAM_TEXT_INFO You have logged in using cached account information.  Some 
network services
  will be unavailable.

  The 'will be unavailable.' part is interpreted as an unknown message
  and causes failed authorization.

[Desktop-packages] [Bug 1510824] Re: PolkitAgentSession incorrectly handles multiline output (as observed with pam_vas)

[Dariusz Gadomski]

I have prepared a 'broken' pam_unix version printing a multiline text info if 
it detects the PAM_SERVICE name is polkit-1.
This allows to reproduce the issue and verify the fix.

I've made this broken version available for Vivid and Wily in
ppa:dgadomski/lp1510824 and performed the verification for those
releases.

In both cases the fix solves the problem and I haven't observed any
regressions. Updating tags.

[Desktop-packages] [Bug 1510824] Re: PolkitAgentSession incorrectly handles multiline output (as observed with pam_vas)

[Chris J Arges]

Hello Dariusz, or anyone else affected,

Accepted policykit-1 into trusty-proposed. The package will build now
and be available at
https://launchpad.net/ubuntu/+source/policykit-1/0.105-4ubuntu3.14.04.1
in a few hours, and then in the -proposed repository.

Please help us by testing this new package.  See
https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to
enable and use -proposed.  Your feedback will aid us getting this update
out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug,
mentioning the version of the package you tested, and change the tag
from verification-needed to verification-done. If it does not fix the
bug for you, please add a comment stating that, and change the tag to
verification-failed.  In either case, details of your testing will help
us make a better decision.

Further information regarding the verification process can be found at
https://wiki.ubuntu.com/QATeam/PerformingSRUVerification .  Thank you in
advance!

Bug description:
  [Impact]

   * Some PAM modules produce output of more than 1 line (e.g.
  PAM_TEXT_INFO may contain newlines in the message content). Polkit
  authentication agent is prepared to receive only single-line messages
  so it treats each line as a separate message. It fails to recognize
  the type of message for all of them except the first - hence failed
  authorization even if it was successful on the PAM-level.

   * The PAM specification does not require the modules to send only
  single-line messages. Thus, polkit needs to be fixed.

  * The helper component should escape (g_strescape) all messages before
  sending it up to the authentication agent. This way everything will be
  read as a single line and then unescaped to restore it's formatting
  with no changes required in PAM modules.

  [Test Case]

   * Use a pam module that returns a multi-line PAM_TEXT_INFO message on
  successful authentication (may require to artificially modify a pam
  module).

   * Perform a polkit authorization with e.g. pkexec ls

   * Correct authorization should end with a failure with an
  unrecognized PAM message

  [Regression Potential]

   * Fix makes advantage of the fact that polkit authentication agent
  already un-escapess (g_strcompress) all input from the helper
  component.

  * Fix is a backport of an upstream change.

  [Other Info]

   * Original bug description:

  There is an error observed when Ubuntu is configured to perform
  authentication via pam_vas (Vintela Authentication Services by Dell)
  in a disconnected mode (using cached authentication).

  Steps to reproduce:
  1. Configure pam_vas client authenticating to a remote server.
  2. Perform authentication to cache the credentials.
  3. Disconnect from the network where the server is reachable (to force using 
cached information).
  4. Perform an action requiring polkit authentication.

  Expected result:
  Authentication succeeds accompanied by the following message "You have logged 
in using cached account information.  Some network services will be 
unavailable".

  Actual result:
  Authentication fails accompanied by the following message "You have logged in 
using cached account information.  Some network services will be unavailable".

  Probable cause:
  The PolkitAgentSession part of polkit is designed to interpret only 1-line 
output, while interaction with pam_vas in the above scenario triggers helper to 
produce the following 2-line output:
  PAM_TEXT_INFO You have logged in using cached account information.  Some 
network services
  will be unavailable.

  The 'will be unavailable.' part is interpreted as an unknown message
  and causes failed authorization.

Daniel uploaded the SRUs already. I'm committing the fix to Debian so
that for xenial we can stay in sync.

Thanks Dariusz!

  There is an error observed when Ubuntu is configured to perform
  authentication via pam_vas (Vintela Authentication Services by Dell) in
  a disconnected mode (using cached authentication).
  
  Steps to reproduce:
  1. Configure pam_vas client authenticating to a remote server.
  2. Perform authentication to cache the credentials.
  3. Disconnect from the network where the server is reachable (to force using 
cached information).
  4. Perform an action requiring polkit authentication.
  
  Expected result:
  Authentication succeeds accompanied by the following message "You have logged 
in using cached account information.  Some network services will be 
unavailable".
  
  Actual result:
  Authentication fails accompanied by the following message "You have logged in 
using cached account information.  Some network services will be unavailable".
  
  Probable cause:
  The PolkitAgentSession part of polkit is designed to interpret only 1-line 
output, while interaction with pam_vas in the above scenario triggers helper to 
produce the following 2-line output:
  PAM_TEXT_INFO You have logged in using cached account information.  Some 
network services
  will be unavailable.
  
  The 'will be unavailable.' part is interpreted as an unknown message and
  causes failed authorization.

Thanks for the patch.

Yes, this is the correct thing to do
(polkitagentsession.c:io_watch_have_data is always calling
g_strcompress()).

Having the same newline handling and escaping code in three places seems
too ugly and unnecessary, though.  Would you be willing to update the
patch so that polkitagenthelper-pam.c uses the send_to_helper function
throughout (modified to do the escaping as necessary), or at least to
test such an updated patch?

  PolkitAgentSession incorrectly handles multiline output (as observed

Bug description:
  There is an error observed when Ubuntu is configured to perform
  authentication via pam_vas (Vintela Authentication Services by Dell)
  in a disconnected mode (using cached authentication).

  Steps to reproduce:
  1. Configure pam_vas client authenticating to a remote server.
  2. Perform authentication to cache the credentials.
  3. Disconnect from the network where the server is reachable (to force using 
cached information).
  4. Perform an action requiring polkit authentication.

  Expected result:
  Authentication succeeds accompanied by the following message "You have logged 
in using cached account information.  Some network services will be 
unavailable".

  Actual result:
  Authentication fails accompanied by the following message "You have logged in 
using cached account information.  Some network services will be unavailable".

  Probable cause:
  The PolkitAgentSession part of polkit is designed to interpret only 1-line 
output, while interaction with pam_vas in the above scenario triggers helper to 
produce the following 2-line output:
  PAM_TEXT_INFO You have logged in using cached account information.  Some 
network services
  will be unavailable.

  The 'will be unavailable.' part is interpreted as an unknown message
  and causes failed authorization.
