Summary

A flaw was found in glusterfs server through versions 4.1.4 and 3.1.2 which allowed repeated usage of GF_META_LOCK_KEY xattr. A remote, authenticated attacker could use this flaw to create multiple locks for single inode by using setxattr repetitively resulting in memory exhaustion of glusterfs server node.

Common Weakness Enumeration (CWE)

Common Attack Pattern Enumeration and Classification (CAPEC)

  • XML Ping of the Death
    An attacker initiates a resource depletion attack where a large number of small XML messages are delivered at a sufficiently rapid rate to cause a denial of service or crash of the target. Transactions such as repetitive SOAP transactions can deplete resources faster than a simple flooding attack because of the additional resources used by the SOAP protocol and the resources necessary to process SOAP messages. The transactions used are immaterial as long as they cause resource utilization on the target. In other words, this is a normal flooding attack augmented by using messages that will require extra processing on the target.
  • XML Entity Expansion
    An attacker submits an XML document to a target application where the XML document uses nested entity expansion to produce an excessively large output XML. XML allows the definition of macro-like structures that can be used to simplify the creation of complex structures. However, this capability can be abused to create excessive demands on a processor's CPU and memory. A small number of nested expansions can result in an exponential growth in demands on memory.
  • Inducing Account Lockout
    An attacker leverages the security functionality of the system aimed at thwarting potential attacks to launch a denial of service attack against a legitimate system user. Many systems, for instance, implement a password throttling mechanism that locks an account after a certain number of incorrect log in attempts. An attacker can leverage this throttling mechanism to lock a legitimate user out of their own account. The weakness that is being leveraged by an attacker is the very security feature that has been put in place to counteract attacks.
  • Violating Implicit Assumptions Regarding XML Content (aka XML Denial of Service (XDoS))
    XML Denial of Service (XDoS) can be applied to any technology that utilizes XML data. This is, of course, most distributed systems technology including Java, .Net, databases, and so on. XDoS is most closely associated with web services, SOAP, and Rest, because remote service requesters can post malicious XML payloads to the service provider designed to exhaust the service provider's memory, CPU, and/or disk space. The main weakness in XDoS is that the service provider generally must inspect, parse, and validate the XML messages to determine routing, workflow, security considerations, and so on. It is exactly these inspection, parsing, and validation routines that XDoS targets. There are three primary attack vectors that XDoS can navigate Target CPU through recursion: attacker creates a recursive payload and sends to service provider Target memory through jumbo payloads: service provider uses DOM to parse XML. DOM creates in memory representation of XML document, but when document is very large (for example, north of 1 Gb) service provider host may exhaust memory trying to build memory objects. XML Ping of death: attack service provider with numerous small files that clog the system. All of the above attacks exploit the loosely coupled nature of web services, where the service provider has little to no control over the service requester and any messages the service requester sends.

"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.

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."

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-2018-14661, 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)"
