Description

From Red Hat Security Advisory 2018:3242 :

An update for glusterfs is now available for Red Hat Enterprise Linux 7.

Red Hat Product Security has rated this update as having a security impact of Moderate. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available for each vulnerability from the CVE link(s) in the References section.

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.

The following packages have been upgraded to a later upstream version: glusterfs (3.12.2). (BZ#1579734)

Security Fix(es) :

  • glusterfs: Improper deserialization in dict.c:dict_unserialize() can allow attackers to read arbitrary memory (CVE-2018-10911)

For more details about the security issue(s), including the impact, a CVSS score, and other related information, refer to the CVE page(s) listed in the References section.

Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting this issue.

Additional Changes :

For detailed information on changes in this release, see the Red Hat Enterprise Linux 7.6 Release Notes linked from the References section.
