Уязвимость системы хранения данных Ceph, существующая из-за недостаточной проверки входных данных, позволяющая нарушителю вызвать отказ в обслуживании

It was found that cephx authentication protocol did not verify ceph clients correctly and was vulnerable to replay attack. Any attacker having access to ceph cluster network who is able to sniff packets on network can use this vulnerability to authenticate with ceph service and perform actions allowed by ceph service. Ceph branches master, mimic, luminous and jewel are believed to be vulnerable.

It was found Ceph versions before 13.2.4 that authenticated ceph users with read only permissions could steal dm-crypt encryption keys used in ceph disk encryption.
