glusterfs server before versions 3.10.12, 4.0.2 is vulnerable when using 'auth.allow' option which allows any unauthenticated gluster client to connect from any network to mount gluster storage volumes. NOTE: this vulnerability exists because of a CVE-2018-1088 regression.

This update for glusterfs fixes the following issues :

glusterfs was update to release 3.12.15 :

  - Fixed a number of bugs and security issues :

  - CVE-2018-1088, CVE-2018-1112 [boo#1090084],     CVE-2018-10904 [boo#1107018], CVE-2018-10907     [boo#1107019], CVE-2018-10911 [boo#1107020],     CVE-2018-10913 [boo#1107021], CVE-2018-10914     [boo#1107022], CVE-2018-10923 [boo#1107023],     CVE-2018-10924 [boo#1107024], CVE-2018-10926     [boo#1107025], CVE-2018-10927 [boo#1107026],     CVE-2018-10928 [boo#1107027], CVE-2018-10928     [boo#1107027], CVE-2018-10929 [boo#1107028],     CVE-2018-10930 [boo#1107029], boo#1105776 .

According to the versions of the glusterfs packages installed, the EulerOS installation on the remote host is affected by the following vulnerabilities :

  - A privilege escalation flaw was found in gluster     snapshot scheduler. Any gluster client allowed to mount     gluster volumes could also mount shared gluster storage     volume and escalate privileges by scheduling malicious     cronjob via symlink.(CVE-2018-1088)

  - It was found that fix for CVE-2018-1088 introduced a     new vulnerability in the way 'auth.allow' is     implemented in glusterfs server. An unauthenticated     gluster client could mount gluster storage     volumes.(CVE-2018-1112)

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

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by a vulnerability as referenced in the RHSA-2018:1269 advisory.

    GlusterFS is a key building block of Red Hat Gluster Storage. It is based on a stackable user-space design     and can deliver exceptional performance for diverse workloads. GlusterFS aggregates various storage     servers over network interconnections into one large, parallel network file system.

    Security Fix(es):

    * It was found that fix for CVE-2018-1088 introduced a new vulnerability in the way 'auth.allow' is     implemented in glusterfs server. An unauthenticated gluster client could mount gluster storage volumes.
    (CVE-2018-1112)
