Уязвимость системы хранения данных Ceph, связанная с ошибкой процедуры авторизации, позволяющая нарушителю получить несанкционированный доступ к ключам шифрования dm-crypt

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

A flaw was found in the way ceph mon handles user requests. Any authenticated ceph user having read access to ceph can delete, create ceph storage pools and corrupt snapshot images. Ceph branches master, mimic, luminous and jewel are believed to be affected.

A flaw was found in the way signature calculation was handled by cephx authentication protocol. An attacker having access to ceph cluster network who is able to alter the message payload was able to bypass signature checks done by cephx protocol. 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.

It was found in Ceph versions before 13.2.4 that authenticated ceph RGW users can cause a denial of service against OMAPs holding bucket indices.

Ceph does not properly sanitize encryption keys in debug logging for v4 auth. This results in the leaking of encryption key information in log files via plaintext. Versions up to v13.2.4 are vulnerable.

In Ceph before 12.2.3 and 13.x through 13.0.1, the rgw_civetweb.cc RGWCivetWeb::init_env function in radosgw doesn't handle malformed HTTP headers properly, allowing for denial of service.
