Description Siddharth Sharma 2015-05-22 08:57:53 UTC

"ceph-deploy admin" command pushes the client.admin key with world readable
permissions as in /etc/ceph/ceph.client.admin.keyring, It is similar issue
like CVE-2015-3010 , but this seems more bad as it is copying to /etc/ceph
which readable by any user.

~]# ls -Z /etc/ | grep ceph
drwxr-xr-x. root root system_u:object_r:etc_t:s0 ceph
