libvirt 0.7.5 through 1.2.x before 1.2.5 allows local users to cause a denial of service (read block and hang) via a crafted XML document containing an XML external entity declaration in conjunction with an entity reference to the (1) virConnectCompareCPU or (2) virConnectBaselineCPU API method, related to an XML External Entity (XXE) issue. NOTE: this issue was SPLIT per ADT3 due to different affected versions of some vectors. CVE-2014-5177 is used for other API methods.
Vulnerable Configurations
Common Weakness Enumeration (CWE)
Common Attack Pattern Enumeration and Classification (CAPEC)
- Buffer Overflow via Environment Variables This attack pattern involves causing a buffer overflow through manipulation of environment variables. Once the attacker finds that they can modify an environment variable, they may try to overflow associated buffers. This attack leverages implicit trust often placed in environment variables.
- Server Side Include (SSI) Injection An attacker can use Server Side Include (SSI) Injection to send code to a web application that then gets executed by the web server. Doing so enables the attacker to achieve similar results to Cross Site Scripting, viz., arbitrary code execution and information disclosure, albeit on a more limited scale, since the SSI directives are nowhere near as powerful as a full-fledged scripting language. Nonetheless, the attacker can conveniently gain access to sensitive files, such as password files, and execute shell commands.
- Cross Zone Scripting An attacker is able to cause a victim to load content into their web-browser that bypasses security zone controls and gain access to increased privileges to execute scripting code or other web objects such as unsigned ActiveX controls or applets. This is a privilege elevation attack targeted at zone-based web-browser security. In a zone-based model, pages belong to one of a set of zones corresponding to the level of privilege assigned to that page. Pages in an untrusted zone would have a lesser level of access to the system and/or be restricted in the types of executable content it was allowed to invoke. In a cross-zone scripting attack, a page that should be assigned to a less privileged zone is granted the privileges of a more trusted zone. This can be accomplished by exploiting bugs in the browser, exploiting incorrect configuration in the zone controls, through a cross-site scripting attack that causes the attackers' content to be treated as coming from a more trusted page, or by leveraging some piece of system functionality that is accessible from both the trusted and less trusted zone. This attack differs from "Restful Privilege Escalation" in that the latter correlates to the inadequate securing of RESTful access methods (such as HTTP DELETE) on the server, while cross-zone scripting attacks the concept of security zones as implemented by a browser.
- Cross Site Scripting through Log Files An attacker may leverage a system weakness where logs are susceptible to log injection to insert scripts into the system's logs. If these logs are later viewed by an administrator through a thin administrative interface and the log data is not properly HTML encoded before being written to the page, the attackers' scripts stored in the log will be executed in the administrative interface with potentially serious consequences. This attack pattern is really a combination of two other attack patterns: log injection and stored cross site scripting.
- Command Line Execution through SQL Injection An attacker uses standard SQL injection methods to inject data into the command line for execution. This could be done directly through misuse of directives such as MSSQL_xp_cmdshell or indirectly through injection of data into the database that would be interpreted as shell commands. Sometime later, an unscrupulous backend application (or could be part of the functionality of the same application) fetches the injected data stored in the database and uses this data as command line arguments without performing proper validation. The malicious data escapes that data plane by spawning new commands to be executed on the host.

NASL family Oracle Linux Local Security Checks NASL id ORACLELINUX_ELSA-2014-0914.NASL description From Red Hat Security Advisory 2014:0914 : Updated libvirt packages that fix one security issue and three bugs are now available for Red Hat Enterprise Linux 7. The Red Hat Security Response Team has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The libvirt library is 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. It was found that libvirt passes the XML_PARSE_NOENT flag when parsing XML documents using the libxml2 library, in which case all XML entities in the parsed documents are expanded. A user able to force libvirtd to parse an XML document with an entity pointing to a file could use this flaw to read the contents of that file; parsing an XML document with an entity pointing to a special file that blocks on read access could cause libvirtd to hang indefinitely, resulting in a denial of service on the system. (CVE-2014-0179) Red Hat would like to thank the upstream Libvirt project for reporting this issue. Upstream acknowledges Daniel P. Berrange and Richard Jones as the original reporters. This update also fixes the following bugs : * A previous update of the libvirt package introduced an error; a SIG_SETMASK argument was incorrectly replaced by a SIG_BLOCK argument after the poll() system call. Consequently, the SIGCHLD signal could be permanently blocked, which caused signal masks to not return to their original values and defunct processes to be generated. With this update, the original signal masks are restored and defunct processes are no longer generated. (BZ#1112689) * An attempt to start a domain that did not exist caused network filters to be locked for read-only access. As a consequence, when trying to gain read-write access, a deadlock occurred. This update applies a patch to fix this bug and an attempt to start a non-existent domain no longer causes a deadlock in the described scenario. (BZ#1112690) * Previously, the libvirtd daemon was binding only to addresses that were configured on certain network interfaces. When libvirtd started before the IPv4 addresses had been configured, libvirtd listened only on the IPv6 addresses.

NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2014-0629.NASL description An updated rhev-hypervisor6 package that fixes two security issues is now available. The Red Hat Security Response Team has rated this update as having Important security impact. Common Vulnerability Scoring System (CVSS) base scores, which give detailed severity ratings, are available for each vulnerability from the CVE links in the References section. The rhev-hypervisor6 package provides a Red Hat Enterprise Virtualization Hypervisor ISO disk image. The Red Hat Enterprise Virtualization Hypervisor is a dedicated Kernel-based Virtual Machine (KVM) hypervisor. It includes everything necessary to run and manage virtual machines: a subset of the Red Hat Enterprise Linux operating environment and the Red Hat Enterprise Virtualization Agent. OpenSSL is a toolkit that implements the Secure Sockets Layer (SSL v2/v3) and Transport Layer Security (TLS v1) protocols, as well as a full-strength, general purpose cryptography library. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. It was found that OpenSSL clients and servers could be forced, via a specially crafted handshake packet, to use weak keying material for communication. A man-in-the-middle attacker could use this flaw to decrypt and modify traffic between a client and a server. (CVE-2014-0224) Note: In order to exploit this flaw, both the server and the client must be using a vulnerable version of OpenSSL; the server must be using OpenSSL version 1.0.1 and above, and the client must be using any version of OpenSSL. For more information about this flaw, refer to: https://access.redhat.com/site/articles/904433 A flaw was found in the way the handle_rx() function handled large network packets when mergeable buffers were disabled. A privileged guest user could use this flaw to crash the host or corrupt QEMU process memory on the host, which could potentially result in arbitrary code execution on the host with the privileges of the QEMU process.

A user able to force libvirtd to parse an XML document with an entity pointing to a file could use this flaw to read the contents of that file; parsing an XML document with an entity pointing to a special file that blocks on read access could cause libvirtd to hang indefinitely, resulting in a denial of service on the system. (CVE-2014-0179) Red Hat would like to thank the upstream Libvirt project for reporting this issue. Upstream acknowledges Daniel P. Berrange and Richard Jones as the original reporters. This update also fixes the following bugs : * A previous update of the libvirt package introduced an error; a SIG_SETMASK argument was incorrectly replaced by a SIG_BLOCK argument after the poll() system call. Consequently, the SIGCHLD signal could be permanently blocked, which caused signal masks to not return to their original values and defunct processes to be generated. With this update, the original signal masks are restored and defunct processes are no longer generated. (BZ#1112689) * An attempt to start a domain that did not exist caused network filters to be locked for read-only access. As a consequence, when trying to gain read-write access, a deadlock occurred. This update applies a patch to fix this bug and an attempt to start a non-existent domain no longer causes a deadlock in the described scenario. (BZ#1112690) * Previously, the libvirtd daemon was binding only to addresses that were configured on certain network interfaces.

This update also fixes the following bugs : * When hot unplugging a virtual CPU (vCPU), libvirt kept a pointer to already freed memory if the vCPU was pinned to a host CPU. Consequently, when reading the CPU pinning information, libvirt terminated unexpectedly due to an attempt to access this memory. This update ensures that libvirt releases the pointer to the previously allocated memory when a vCPU is being hot unplugged, and it no longer crashes in this situation.

The Red Hat Security Response Team has rated this update as having Moderate security impact. A Common Vulnerability Scoring System (CVSS) base score, which gives a detailed severity rating, is available from the CVE link in the References section. The libvirt library is 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. It was found that libvirt passes the XML_PARSE_NOENT flag when parsing XML documents using the libxml2 library, in which case all XML entities in the parsed documents are expanded. A user able to force libvirtd to parse an XML document with an entity pointing to a file could use this flaw to read the contents of that file; parsing an XML document with an entity pointing to a special file that blocks on read access could cause libvirtd to hang indefinitely, resulting in a denial of service on the system. (CVE-2014-0179) Red Hat would like to thank the upstream Libvirt project for reporting this issue. Upstream acknowledges Daniel P. Berrange and Richard Jones as the original reporters. This update also fixes the following bugs : * A previous update of the libvirt package introduced an error; a SIG_SETMASK argument was incorrectly replaced by a SIG_BLOCK argument after the poll() system call. Consequently, the SIGCHLD signal could be permanently blocked, which caused signal masks to not return to their original values and defunct processes to be generated. With this update, the original signal masks are restored and defunct processes are no longer generated. (BZ#1112689) * An attempt to start a domain that did not exist caused network filters to be locked for read-only access. As a consequence, when trying to gain read-write access, a deadlock occurred. This update applies a patch to fix this bug and an attempt to start a non-existent domain no longer causes a deadlock in the described scenario. (BZ#1112690) * Previously, the libvirtd daemon was binding only to addresses that were configured on certain network interfaces. When libvirtd started before the IPv4 addresses had been configured, libvirtd listened only on the IPv6 addresses. The daemon has been modified to not require an address to be configured when binding to a wildcard address, such as last seen 2020-06-01 modified 2020-06-02 plugin id 76904 published 2014-07-30 reporter This script is Copyright (C) 2014-2019 and is owned by Tenable, Inc. or an Affiliate thereof. source https://www.tenable.com/plugins/nessus/76904 title RHEL 7 : libvirt (RHSA-2014:0914) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2014-0560.NASL description Updated libvirt packages that fix one security issue and three bugs are now available for Red Hat Enterprise Linux 6.
