Several vulnerabilities were discovered in Ceph, a distributed storage and file system.

CVE-2018-14662

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

CVE-2018-16846

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

For Debian 8 ‘Jessie’, these problems have been fixed in version 0.80.7-2+deb8u3.

We recommend that you upgrade your ceph packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
