[Touch-packages] [Bug 1648901] Re: SPNEGO crash on mechanism failure

[Andrew Jorgensen]

Tested w/ libkrb5-3=1.13.2+dfsg-5ubuntu2 from xenial-proposed. It was
tricky to prepare an environment I could safely test in, but I verified
that chrome crashed with previous version, but does not crash after
update to the proposed version.

[Touch-packages] [Bug 1648901] Re: SPNEGO crash on mechanism failure

[Eric Desrochers]

@dwmw2,
@Andrew Jorgensen,
or anyone else affected by this bug.

As you may have notice, there is currently a call for testing a proposed
version of the source package "krb5".

This is the last step before the package make its way into xenial-
updates (final destination)

Could you please try the package and provide feedbacks so I can complete
the SRU ?

- Eric

[Touch-packages] [Bug 1648901] Re: SPNEGO crash on mechanism failure

[Andy Whitcroft]

Hello dwmw2, or anyone else affected,

Accepted krb5 into xenial-proposed. The package will build now and be
available at https://launchpad.net/ubuntu/+source/krb5/1.13.2+dfsg-
5ubuntu2 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!

** Changed in: krb5 (Ubuntu Xenial)
   Status: In Progress => Fix Committed

[Touch-packages] [Bug 1648901] Re: SPNEGO crash on mechanism failure

[Eric Desrochers]

As per a irc conversation with the SRU team (apw),

The existing krb5 (1.13.2+dfsg-5ubuntu1) has a regressing ADT test so it stuck 
in -proposed.
Thus, preventing krb5 (1.13.2+dfsg-5ubuntu2) to land in -proposed.

SRU team are looking at this as we speak.

- Eric

dwmw2,

Can you please give a try at this test package ?

Hi andrew, dwmw2 et al,

If I build a test package on Monday, will you be amenable to
install/test it and then provide feedbacks before I start the SRU ?

Addtionnaly, can you provide the detailed steps on how to reproduce the
problem ?
