Re: Security hole in Axis2 1.4 + Rampart 1.4
Hi,
For the users who is already using 1.4 version, the workaround would be to
define policies in services.xml without using <wsa:PolicyAttachment>. Then
the problem is that those policies will appear in <wsdl:PortType> which is
not correct but security will apply for both format of service URLs.
Hence +1 for fixing that issue and do 1.4.1 release.
Thanks,
Sanka

I would like to volunteer to be the release manager for Axis2 1.4.1.
I think we can fix the critical issues in the 1.4 branch (or a 1.4.1 branch
) and do the 1.4.1 release. I don't think doing 1.4.1 from the trunk is the
appropriate way as trunk is now java 1.5 and has lot of major changes after
Axis2 1.4 . However we can fix any issues that are not already fixed in the
trunk at the same time when we fix those in the branch.
Hope this is oky with Axis2 release guidelines.
thanks,
nandana

IMHO, The logic is the same as for blockers. If there is a work
around, it's not a blocker. So i am +0 on a 1.4.1 since there is a
work around that can be documented.
That said, If someone is willing to drive a 1.4.1 as the release
manager, please do go ahead.
thanks,
