Vulnerable Configurations
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.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2018-1396.NASL description An update for libvirt is now available for Red Hat Enterprise Linux 7. Red Hat Product Security has rated this update as having a security impact of Low. 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. The libvirt library contains a C API for managing and interacting with the virtualization capabilities of Linux and other operating systems. In addition, libvirt provides tools for remote management of virtualized systems. Security Fix(es) : * libvirt: Resource exhaustion via qemuMonitorIORead() method (CVE-2018-5748) * libvirt: Incomplete fix for CVE-2018-5748 triggered by QEMU guest agent (CVE-2018-1064) 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. The CVE-2018-1064 issue was discovered by Daniel P. Berrange (Red Hat) and the CVE-2018-5748 issue was discovered by Daniel P. Berrange (Red Hat) and Peter Krempa (Red Hat). Bug Fix(es) : * Previously, the check for a non-unique device boot order did not properly handle updates of existing devices when a new device was attached to a guest. Consequently, updating any device with a specified boot order failed. With this update, the duplicity check detects correctly handles updates and ignores the original device, which avoids reporting false conflicts. As a result, updating a device with a boot order succeeds. (BZ# 1557922) * In Red Hat Enterprise Linux 7.5, guests with SCSI passthrough enabled failed to boot because of changes in kernel CGroup detection. With this update, libvirt fetches dependencies and adds them to the device CGroup. As a result, and the affected guests now start as expected. (BZ#1564996) * The VMX parser in libvirt did not parse more than four network interfaces. As a consequence, the esx driver did not expose more than four network interface cards (NICs) for guests running ESXi. With this update, the VMX parser parses all the available NICs in .vmx files. As a result, libvirt reports all the NICs of guests running ESXi. (BZ#1566524) * Previously, user aliases for PTY devices that were longer than 32 characters were not supported. Consequently, if a domain included a PTY device with a user alias longer than 32 characters, the domain would not start. With this update, a static buffer was replaced with a dynamic buffer. As a result, the domain starts even if the length of the user alias for a PTY device is longer than 32 characters.

Berrang (Red Hat) and the CVE-2018-5748 issue was discovered by Daniel P. Berrange (Red Hat) and Peter Krempa (Red Hat). Bug Fix(es) : - Previously, the check for a non-unique device boot order did not properly handle updates of existing devices when a new device was attached to a guest. Consequently, updating any device with a specified boot order failed. With this update, the duplicity check detects correctly handles updates and ignores the original device, which avoids reporting false conflicts. As a result, updating a device with a boot order succeeds. - In Scientific Linux 7.5, guests with SCSI passthrough enabled failed to boot because of changes in kernel CGroup detection. With this update, libvirt fetches dependencies and adds them to the device CGroup. As a result, and the affected guests now start as expected. - The VMX parser in libvirt did not parse more than four network interfaces. As a consequence, the esx driver did not expose more than four network interface cards (NICs) for guests running ESXi. With this update, the VMX parser parses all the available NICs in .vmx files. As a result, libvirt reports all the NICs of guests running ESXi. - Previously, user aliases for PTY devices that were longer than 32 characters were not supported. Consequently, if a domain included a PTY device with a user alias longer than 32 characters, the domain would not start. With this update, a static buffer was replaced with a dynamic buffer. As a result, the domain starts even if the length of the user alias for a PTY device is longer than 32 characters. last seen 2020-03-18 modified 2018-05-16 plugin id 109853 published 2018-05-16 reporter This script is Copyright (C) 2018-2020 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/109853 title Scientific Linux Security Update : libvirt on SL7.x x86_64 (20180515)
