A flaw was found in Grafana 2.x, 3.x, and 4.x before 4.6.4 and 5.x before 5.2.3 allows authentication bypass because an attacker can generate a valid "remember me" cookie knowing only a username of an LDAP or OAuth user.

A key length flaw was found in Red Hat Ceph Storage. An attacker can exploit the fact that the key length is incorrectly passed in an encryption algorithm to create a non random key, which is weaker and can be exploited for loss of confidentiality and integrity on encrypted disks.

A flaw was found in Red Hat Ceph Storage version 3 in the way the Ceph RADOS Gateway daemon handles S3 requests. An authenticated attacker can abuse this flaw by causing a remote denial of service by sending a specially crafted HTTP Content-Length header to the Ceph RADOS Gateway server.

A flaw was found in Ceph, relating to the URL processing on RGW backends. An attacker can exploit the URL processing by providing a null URL to crash the RGW, causing a denial of service.
