Synopsis

The remote Ubuntu host is missing one or more security updates.

Description

The remote Ubuntu 14.04 LTS / 16.04 LTS host has packages installed that are affected by multiple vulnerabilities as referenced in the USN-7706-1 advisory.

 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 14.04 LTS. (CVE-2018-14662)

 Sergey Bobrov discovered that Cephs RadosGW (Ceph Object Gateway) allowed the injection of HTTP headers in responses to CORS requests. An attacker could possibly use this issue to compromise system integrity.
 This issue only affected Ubuntu 16.04 LTS. (CVE-2021-3524)

Tenable has extracted the preceding description block directly from the Ubuntu security advisory.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
