CVE-2018-14662 [MEDIUM] Ceph vulnerabilities
Title: Ceph vulnerabilities
Summary: Several security issues were fixed in Ceph.
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. (CVE-2018-14662)
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.
(CVE-2018-16846)
It was discovered that Ceph incorrectly sanitized certain debug logs. A
local attacker could possibly use this issue to obtain encryption key
information. This issue was only addressed in Ubuntu 18.10 and Ubuntu
