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 6.

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.

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.

This update provides the following 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.

The remote Debian 9 host has packages installed that are affected by multiple vulnerabilities as referenced in the dla-2806 advisory.

    Multiple security vulnerabilities were discovered in GlusterFS, a clustered file system. Buffer overflows     and path traversal issues may lead to information disclosure, denial-of-service or the execution of     arbitrary code. For Debian 9 stretch, these problems have been fixed in version 3.8.8-1+deb9u1. We     recommend that you upgrade your glusterfs packages. For the detailed security status of glusterfs please     refer to its security tracker page at: https://security-tracker.debian.org/tracker/glusterfs Further     information about Debian LTS security advisories, how to apply these updates to your system and frequently     asked questions can be found at: https://wiki.debian.org/LTS

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The remote Redhat Enterprise Linux 7 host has packages installed that are affected by multiple vulnerabilities as referenced in the RHSA-2018:3470 advisory.

    The redhat-virtualization-host packages provide the Red Hat Virtualization Host. These packages include     redhat-release-virtualization-host, ovirt-node, and rhev-hypervisor. Red Hat Virtualization Hosts (RHVH)     are installed using a special build of Red Hat Enterprise Linux with only the packages required to host     virtual machines. RHVH features a Cockpit user interface for monitoring the host's resources and     performing administrative tasks.

    Security Fix(es):

    * spice: Missing check in demarshal.py:write_validate_array_item() allows for buffer overflow and denial     of service (CVE-2018-10873)

    * glusterfs: Multiple flaws (CVE-2018-10904, CVE-2018-10907, CVE-2018-10923, CVE-2018-10926,     CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, CVE-2018-10911, CVE-2018-10914,     CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659, CVE-2018-14660, CVE-2018-14661,     CVE-2018-10913)

    * samba: Insufficient input validation in libsmbclient (CVE-2018-10858)

    Red Hat would like to thank Michael Hanselmann (hansmi.ch) for reporting CVE-2018-10904, CVE-2018-10907,     CVE-2018-10923, CVE-2018-10926, CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930,     CVE-2018-10911, CVE-2018-10914, CVE-2018-14652, CVE-2018-14653, CVE-2018-14654, CVE-2018-14659,     CVE-2018-14660, CVE-2018-14661, and CVE-2018-10913. The CVE-2018-10873 issue was discovered by Frediano     Ziglio (Red Hat).

    Bug Fix(es):

    * When upgrading Red Hat Virtualization Host (RHVH), imgbased fails to run garbage collection on previous     layers, so new logical volumes are removed, and the boot entry points to a logical volume that was     removed.

    If the RHVH upgrade finishes successfully, the hypervisor boots successfully, even if garbage collection     fails. (BZ#1632058)

    * During the upgrade process, when lvremove runs garbage collection, it prompts for user confirmation,     causing the upgrade process to fail. Now the process uses lvremove --force when trying to remove logical     volumes and does not fail even if garbage collection fails, and as a result, the upgrade process finishes     successfully. (BZ#1632585)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

Multiple security vulnerabilities were discovered in GlusterFS, a clustered file system. Buffer overflows and path traversal issues may lead to information disclosure, denial of service or the execution of arbitrary code.

CVE-2018-14651

It was found that the fix for CVE-2018-10927, CVE-2018-10928, CVE-2018-10929, CVE-2018-10930, and CVE-2018-10926 was incomplete. A remote, authenticated attacker could use one of these flaws to execute arbitrary code, create arbitrary files, or cause denial of service on glusterfs server nodes via symlinks to relative paths.

CVE-2018-14652

The Gluster file system is vulnerable to a buffer overflow in the 'features/index' translator via the code handling the 'GF_XATTR_CLRLK_CMD' xattr in the 'pl_getxattr' function. A remote authenticated attacker could exploit this on a mounted volume to cause a denial of service.

CVE-2018-14653

The Gluster file system is vulnerable to a heap-based buffer overflow in the '__server_getspec' function via the 'gf_getspec_req' RPC message. A remote authenticated attacker could exploit this to cause a denial of service or other potential unspecified impact.

CVE-2018-14659

The Gluster file system is vulnerable to a denial of service attack via use of the 'GF_XATTR_IOSTATS_DUMP_KEY' xattr. A remote, authenticated attacker could exploit this by mounting a Gluster volume and repeatedly calling 'setxattr(2)' to trigger a state dump and create an arbitrary number of files in the server's runtime directory.

CVE-2018-14661

It was found that usage of snprintf function in feature/locks translator of glusterfs server was vulnerable to a format string attack. A remote, authenticated attacker could use this flaw to cause remote denial of service.

For Debian 8 'Jessie', these problems have been fixed in version 3.5.2-2+deb8u5.

We recommend that you upgrade your glusterfs packages.
