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.

The following security issues have been fixed : - A locking problem in transparent hugepage support could be used by local attackers to potentially crash the host, or via kvm a privileged guest user could crash the kvm host system. (CVE-2012-1179) - A potential hypervisor escape by issuing SG_IO commands to partitiondevices was fixed by restricting access to these commands. (CVE-2011-4127) - A local attacker could oops the kernel using memory control groups and eventfds. (CVE-2012-1146) - Limit the path length users can build using epoll() to avoid local attackers consuming lots of kernel CPU time. (CVE-2011-1083) - The regset common infrastructure assumed that regsets would always have .get and .set methods, but necessarily .active methods. Unfortunately people have since written regsets without .set method, so NULL pointer dereference attacks were possible. (CVE-2012-1097) - Access to the /proc/pid/taskstats file requires root access to avoid side channel (timing keypresses etc.) attacks on other users. (CVE-2011-2494) - Fixed a oops in jbd/jbd2 that could be caused by specific filesystem access patterns. (CVE-2011-4086) - A malicious NFSv4 server could have caused a oops in the nfsv4 acl handling. (CVE-2011-4131) - Fixed a oops in jbd/jbd2 that could be caused by mounting a malicious prepared filesystem. (Also included are all fixes from the 3.0.14 -> 3.0.25 stable kernel updates.).

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. Note: Red Hat Enterprise Virtualization Hypervisor is only available for the Intel 64 and AMD64 architectures with virtualization extensions. A flaw was found in the way libtasn1 decoded DER data. An attacker could create carefully-crafted DER encoded input (such as an X.509 certificate) that, when parsed by an application that uses libtasn1 (such as applications using GnuTLS), could cause the application to crash. (CVE-2012-1569) A flaw was found in the way GnuTLS decrypted malformed TLS records. This could cause a TLS/SSL client or server to crash when processing a specially crafted TLS record from a remote TLS/SSL connection peer. (CVE-2012-1573) An integer overflow flaw was found in the implementation of the printf functions family. This could allow an attacker to bypass FORTIFY_SOURCE protections and execute arbitrary code using a format string flaw in an application, even though these protections are expected to limit the impact of such flaws to an application abort. (CVE-2012-0864) Red Hat would like to thank Matthew Hall of Mu Dynamics for reporting CVE-2012-1569 and CVE-2012-1573. This updated package provides updated components that include fixes for various security issues. These issues have no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers : CVE-2011-4128 (gnutls issue) CVE-2012-0879, CVE-2012-1090, and CVE-2012-1097 (kernel issues) CVE-2012-0884 and CVE-2012-1165 (openssl issues) CVE-2012-0060, CVE-2012-0061, and CVE-2012-0815 (rpm issues) This update also fixes the following bug : * The Hypervisor previously set the lro_disable option for the enic driver. The driver does not support this option, as a result the Hypervisor did not correctly detect and configure the network interfaces of a Cisco M81KR adaptor, when present. The Hypervisor has been updated and no longer sets the invalid option for this driver. (BZ#809463) Users of Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues. last seen 2020-06-01 modified 2020-06-02 plugin id 78922 published 2014-11-08 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/78922 title RHEL 6 : rhev-hypervisor6 (RHSA-2012:0531) NASL family Red Hat Local Security Checks NASL id REDHAT-RHSA-2012-0481.NASL description Updated kernel packages that fix multiple security issues, several bugs, and add various enhancements are now available for Red Hat Enterprise Linux 6.
