Description Pedro Sampaio 2017-11-21 14:10:10 UTC 
A flaw was discovered in ceph. Assertion in rgw_iam_policy.cc can be reached by user input and fail through data passed in from a rest call causing it to crash.

Upstream patch:

Created ceph tracking bugs for this issue:

Affects: epel-6 [bug 1515896]

Comment 2 Siddharth Sharma 2017-11-21 15:05:16 UTC 
Analysis:

Red Hat Ceph Storage 1.3 and Red Hat Ceph Storage 2 are not affected by this flaw as bucket policy is not supported in ceph version shipped with these products.
