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 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. OpenSSH is OpenBSD's Secure Shell (SSH) protocol implementation. These packages include the core files necessary for the OpenSSH client and server. Due to the way the pam_ssh_agent_auth PAM module was built in Red Hat Enterprise Linux 6, the glibc's error() function was called rather than the intended error() function in pam_ssh_agent_auth to report errors. As these two functions expect different arguments, it was possible for an attacker to cause an application using pam_ssh_agent_auth to crash, disclose portions of its memory or, potentially, execute arbitrary code. (CVE-2012-5536) Note that the pam_ssh_agent_auth module is not used in Red Hat Enterprise Linux 6 by default. This update also fixes the following bugs : * All possible options for the new RequiredAuthentications directive were not documented in the sshd_config man page. This update improves the man page to document all the possible options. (BZ#821641) * When stopping one instance of the SSH daemon (sshd), the sshd init script (/etc/rc.d/init.d/sshd) stopped all sshd processes regardless of the PID of the processes. This update improves the init script so that it only kills processes with the relevant PID. As a result, the init script now works more reliably in a multi-instance environment. (BZ#826720) * Due to a regression, the ssh-copy-id command returned an exit status code of zero even if there was an error in copying the key to a remote host. With this update, a patch has been applied and ssh-copy-id now returns a non-zero exit code if there is an error in copying the SSH certificate to a remote host. (BZ#836650) * When SELinux was disabled on the system, no on-disk policy was installed, a user account was used for a connection, and no '~/.ssh' configuration was present in that user's home directory, the SSH client terminated unexpectedly with a segmentation fault when attempting to connect to another system. A patch has been provided to address this issue and the crashes no longer occur in the described scenario. (BZ#836655) * The 'HOWTO' document /usr/share/doc/openssh-ldap-5.3p1/HOWTO.ldap-keys incorrectly documented the use of the AuthorizedKeysCommand directive. This update corrects the document. (BZ#857760) This update also adds the following enhancements : * When attempting to enable SSH for use with a Common Access Card (CAC), the ssh-agent utility read all the certificates in the card even though only the ID certificate was needed. Consequently, if a user entered their PIN incorrectly, then the CAC was locked, as a match for the PIN was attempted against all three certificates. With this update, ssh-add does not try the same PIN for every certificate if the PIN fails for the first one. As a result, the CAC will not be disabled if a user enters their PIN incorrectly. (BZ#782912) * This update adds a 'netcat mode' to SSH. The 'ssh -W host:port ...' command connects standard input and output (stdio) on a client to a single port on a server. As a result, SSH can be used to route connections via intermediate servers. (BZ#860809) * Due to a bug, arguments for the RequiredAuthentications2 directive were not stored in a Match block. Consequently, parsing of the config file was not in accordance with the man sshd_config documentation. This update fixes the bug and users can now use the required authentication feature to specify a list of authentication methods as expected according to the man page. (BZ#869903) All users of openssh are advised to upgrade to these updated packages, which fix these issues and add these enhancements. After installing this update, the OpenSSH server daemon (sshd) will be restarted automatically." ); script_set_attribute( attribute:"see_also", value:"https://oss.oracle.com/pipermail/el-errata/2013-February/003286.html" ); script_set_attribute( attribute:"solution", value:"Update the affected openssh packages." ); script_set_cvss_base_vector("CVSS2#AV:L/AC:H/Au:N/C:C/I:C/A:C"); script_set_cvss_temporal_vector("CVSS2#E:U/RL:OF/RC:C"); script_set_attribute(attribute:"exploitability_ease", value:"No known exploits are available"); script_set_attribute(attribute:"exploit_available", value:"false"); script_set_attribute(attribute:"plugin_type", value:"local"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:oracle:linux:openssh"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:oracle:linux:openssh-askpass"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:oracle:linux:openssh-clients"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:oracle:linux:openssh-ldap"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:oracle:linux:openssh-server"); script_set_attribute(attribute:"cpe", value:"p-cpe:/a:oracle:linux:pam_ssh_agent_auth"); script_set_attribute(attribute:"cpe", value:"cpe:/o:oracle:linux:6"); script_set_attribute(attribute:"vuln_publication_date", value:"2013/02/21"); script_set_attribute(attribute:"patch_publication_date", value:"2013/02/25"); script_set_attribute(attribute:"plugin_publication_date", value:"2013/07/12"); script_set_attribute(attribute:"generated_plugin", value:"current"); script_end_attributes(); script_category(ACT_GATHER_INFO); script_copyright(english:"This script is Copyright (C) 2013-2019 and is owned by Tenable, Inc. or an Affiliate thereof."); script_family(english:"Oracle Linux Local Security Checks"); script_dependencies("ssh_get_info.nasl"); script_require_keys("Host/local_checks_enabled", "Host/OracleLinux", "Host/RedHat/release", "Host/RedHat/rpm-list"); exit(0); } include("audit.inc"); include("global_settings.inc"); include("rpm.inc"); if (!get_kb_item("Host/local_checks_enabled")) audit(AUDIT_LOCAL_CHECKS_NOT_ENABLED); if (!get_kb_item("Host/OracleLinux")) audit(AUDIT_OS_NOT, "Oracle Linux"); release = get_kb_item("Host/RedHat/release"); if (isnull(release) || !pregmatch(pattern: "Oracle (?:Linux Server|Enterprise Linux)", string:release)) audit(AUDIT_OS_NOT, "Oracle Linux"); os_ver = pregmatch(pattern: "Oracle (?:Linux Server|Enterprise Linux) .*release ([0-9]+(\.[0-9]+)?)", string:release); if (isnull(os_ver)) audit(AUDIT_UNKNOWN_APP_VER, "Oracle Linux"); os_ver = os_ver[1]; if (!

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 the vhost kernel module handled descriptors that spanned multiple regions. A privileged guest user could use this flaw to crash the host or, potentially, escalate their privileges on the host. (CVE-2013-0311) It was found that the default SCSI command filter does not accommodate commands that overlap across device classes. A privileged guest user could potentially use this flaw to write arbitrary data to a LUN that is passed-through as read-only. (CVE-2012-4542) It was discovered that dnsmasq, when used in combination with certain libvirtd configurations, could incorrectly process network packets from network interfaces that were intended to be prohibited. A remote, unauthenticated attacker could exploit this flaw to cause a denial of service via DNS amplification attacks. (CVE-2012-3411) The CVE-2012-4542 issue was discovered by Paolo Bonzini of Red Hat. This updated package provides updated components that include fixes for several security issues. These issues had no security impact on Red Hat Enterprise Virtualization Hypervisor itself, however. The security fixes included in this update address the following CVE numbers : CVE-2012-3955 (dhcp issue) CVE-2011-4355 (gdb issue) CVE-2012-4508, CVE-2013-0190, CVE-2013-0309, and CVE-2013-0310 (kernel issues) CVE-2012-5536 (openssh issue) CVE-2011-3148 and CVE-2011-3149 (pam issues) CVE-2013-0157 (util-linux-ng issue) This updated Red Hat Enterprise Virtualization Hypervisor package also fixes the following bugs : * Previously, the Administration Portal would always display the option to upgrade the Red Hat Enterprise Virtualization Hypervisor ISO regardless of whether or not the selected host was up-to-date. Now, the VDSM version compatibility is considered and the upgrade message only displays if there is an upgrade relevant to the host available. (BZ#853092) * An out of date version of libvirt was included in the Red Hat Enterprise Virtualization Hypervisor 6.4 package. As a result, virtual machines with supported CPU models were not being properly parsed by libvirt and failed to start. A more recent version of libvirt has been included in this updated hypervisor package. Virtual machines now start normally. (BZ#895078) As well, this update adds the following enhancement : * Hypervisor packages now take advantage of the installonlypkg function provided by yum. This allows for multiple versions of the hypervisor package to be installed on a system concurrently without making changes to the yum configuration as was previously required. (BZ#863579) This update includes the ovirt-node build from RHBA-2013:0556 : https://rhn.redhat.com/errata/RHBA-2013-0556.html Users of the Red Hat Enterprise Virtualization Hypervisor are advised to upgrade to this updated package, which fixes these issues and adds this enhancement. last seen 2020-06-01 modified 2020-06-02 plugin id 78950 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/78950 title RHEL 6 : rhev-hypervisor6 (RHSA-2013:0579)
