====================================================================
1. Summary:

Updated glusterfs packages that fix multiple security issues and bugs are
now available for Red Hat Gluster Storage 3.4 on Red Hat Enterprise Linux
7.

Red Hat Product Security has rated this update as having a security impact
of Important. 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.

2. Relevant releases/architectures:

Red Hat Gluster Storage Server 3.4 on RHEL-7 - noarch, x86_64
Red Hat Storage Native Client for Red Hat Enterprise Linux 7 - x86_64

3. Description:

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):

* glusterfs: glusterfs server exploitable via symlinks to relative paths
(CVE-2018-14651)

* glusterfs: Buffer overflow in "features/locks" translator allows for
denial of service (CVE-2018-14652)

* glusterfs: Heap-based buffer overflow via "gf_getspec_req" RPC message
(CVE-2018-14653)

* glusterfs: "features/index" translator can create arbitrary, empty files
(CVE-2018-14654)

* glusterfs: Unlimited file creation via "GF_XATTR_IOSTATS_DUMP_KEY" xattr
allows for denial of service (CVE-2018-14659)

* glusterfs: Repeat use of "GF_META_LOCK_KEY" xattr allows for memory
exhaustion (CVE-2018-14660)

* glusterfs: features/locks translator passes an user-controlled string to
snprintf without a proper format string resulting in a denial of service
(CVE-2018-14661)

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
these issues.

Bug Fix(es):

* MD5 instances are replaced with FIPS-compliant SHA256 checksums and
glusterd no longer crashes when run on a FIPS enabled machine. (BZ#1459709)

* The flock is unlocked specifically and the status file is updated so that
the reference is not leaked to any worker or agent process. As a result of
this fix, all workers come up without fail. (BZ#1623749)

* All HTIME index files are checked for the specified start and end times,
and the History API does not fail when multiple HTIME files exist.
(BZ#1627639)

* After upgrading to Red Hat Gluster Storage 3.4 from earlier versions of
Red Hat Gluster Storage, the volume size displayed by the df command was
smaller than the actual volume size. This has been fixed and the df command
now shows the correct size for all volumes. (BZ#1630997)

* The algorithm to disable the eager-lock is modified and it disables only
when multiple write operations are trying to modify a file at the same
time. This led to performance improvement while a write operation is
performed on a file irrespective of the number of times it is opened at the
same time for a read operation. (BZ#1630688)

* heal-info does not consider the presence of dirty markers as an
indication of split-brain and does not display these entries to be in a
split-brain state. (BZ#1610743)

All users of Red Hat Gluster Storage are advised to upgrade to these
updated packages, which provide numerous bug fixes and enhancements.
