Hi,
[ Reason ]
CVE-2023-43040
[ Impact ]
security issue with RGW with improperly verified POST keys.
[ Tests ]
Upstream runs an extensive unit and functional test suite.
[ Risks ]
There's no modification of the code, just a move of a small
block of code to the appropriate location. So I believe the
risk is minimal.
[ Checklist ]
[x] *all* changes are documented in the d/changelog
[x] I reviewed all changes and I approve them
[x] attach debdiff against the package in (old)stable
[x] the issue is verified as fixed in unstable
[ Changes ]
Just the upstream patch as per the debdiff.
[ Other info ]
Note that the debdiff shows changes in the src/test/debian-jessie
and src/test/ubuntu-16.04 folders. These are generated by the
upstream code, and fixing these would be IMO unecessary effort to
change something that has no consequence on the generated binaries.
So please ignore these.

+Description: CVE-2023-43040 rgw: Fix bucket validation against POST policies
+ It's possible that user could provide a form part as a part of a POST
+ object upload that uses 'bucket' as a key; in this case, it was
+ overriding what was being set in the validation env (which is the real
+ bucket being modified). The result of this is that a user could actually
+ upload to any bucket accessible by the specified access key by matching
+ the bucket in the POST policy in said POST form part.
+ .
+ Fix this simply by setting the bucket to the correct value after the
+ POST form parts are processed, ignoring the form part above if
+ specified.
