Descriptions

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.

Ceph no sanea de manera correcta las claves de cifrado en registros de depuración para autenticaciones v4. Esto resulta en el filtrado de información sobre las claves de cifrado en los archivos de registro mediante texto plano. Las versiones hasta la v13.2.4 son vulnerables.

It was found that Ceph RGW did not properly sanitize encryption keys in debug logging for v4 auth. Encryption keys could be inadvertently disclosed when sharing debug logs.

It was discovered that Ceph incorrectly handled read only permissions. An authenticated attacker could use this issue to obtain dm-crypt encryption keys. This issue only affected Ubuntu 16.04 LTS. It was discovered that Ceph incorrectly handled certain OMAPs holding bucket indices. An authenticated attacker could possibly use this issue to cause a denial of service. This issue only affected Ubuntu 16.04 LTS. Various other issues were also addressed.
