Vulnerability from variot

The redirection implementation in parse.y in GNU Bash through 4.3 bash43-026 allows remote attackers to cause a denial of service (out-of-bounds array access and application crash) or possibly have unspecified other impact via crafted use of here documents, aka the "redir_stack" issue. GNU Bash 4.3 and earlier contains a command injection vulnerability that may allow remote code execution. GNU Bash is prone to a local memory-corruption vulnerability. An attacker can exploit this issue to execute arbitrary code within the context of the affected application. Failed exploit attempts will result in a denial-of-service condition. GNU Bash 3.2 and later are vulnerable; prior versions may also be affected.

NOTE: This vulnerability can only be exploited if the attacker already has valid administrative login credentials. -----BEGIN PGP SIGNED MESSAGE-----

CA20141001-01: Security Notice for Bash Shellshock Vulnerability

Issued: October 01, 2014 Updated: October 03, 2014

CA Technologies is investigating multiple GNU Bash vulnerabilities, referred to as the "Shellshock" vulnerabilities, which were publicly disclosed on September 24-27, 2014. CVE identifiers CVE-2014-6271, CVE-2014-7169, CVE-2014-7186, CVE-2014-7187, CVE-2014-6277, and CVE-2014-6278 have been assigned to these vulnerabilities.

The CA Technologies Enterprise Information Security team has led a global effort to identify and remediate systems and products discovered with these vulnerabilities. We continue to patch our systems as fixes become available, and we are providing fixes for affected CA Technologies products.

CA Technologies continues to aggressively scan our environments (including servers, networks, external facing applications, and SaaS environments) to proactively monitor, identify, and remediate any vulnerability when necessary.

Risk Rating

High

Platform

AIX Android (not vulnerable, unless rooted) Apple iOS (not vulnerable unless jailbroken) Linux Mac OS X Solaris Windows (not vulnerable unless Cygwin or similar ported Linux tools with Bash shell are installed) Other UNIX/BSD based systems if Bash is installed Any other OS or JeOS that utilizes Bash

Affected Products

The following products have been identified as potentially vulnerable, and we have made fixes available for all of these products.

CA API Management (Linux appliance only)

CA Application Performance Management (TIM is the only affected APM component)

CA Application Performance Management Cloud Monitor

CA Customer Experience Manager (CEM) Transaction Impact Monitor (TIM)

CA Layer 7 products (API Gateway, Mobile Access Gateway, API Management Portal)

CA User Activity Reporting Module (Enterprise Log Manager)

Note: This security notice will be updated if other CA Technologies products are determined to be vulnerable.

In most cases, the Bash vulnerabilities will need to be patched by OS vendors. Exceptions may include CA Technologies appliances, and software products that include Linux, UNIX or Mac OS X based operating systems (that include Bash).

Affected Components

CentOS Cygwin GNU Bash Red Hat Enterprise Linux SUSE Linux

Non-Affected Products

IMPORTANT NOTE: This listing includes only a small subset of the unaffected CA Technologies products. We're including unaffected products that customers have already inquired about. While the following CA Technologies products are not directly affected by the Bash vulnerabilities, the underlying operating systems that CA Technologies software is installed on may be vulnerable. We strongly encourage our customers to follow the recommendations provided by their vendors for all operating systems they utilize.

All CA SaaS / On Demand products were either not vulnerable or have already been patched.

CA AHS / PaymentMinder - AHS App is not vulnerable. The AHS app does not execute CGI scripts, or spawn or execute shell commands from within the app. AHS infrastructure already patched.

CA Asset Portfolio Management

CA AuthMinder (Arcot WebFort)

CA AuthMinder for Business Users

CA AuthMinder for Consumers

CA AutoSys products - We use the bash shell that comes with the operating system and the customer is responsible for patching their OS. Additionally, the agents themselves do not distribute any scripts that use bash.

CA Clarity On Demand

CA CloudMinder - CloudMinder does not include the Bash Shell in BoM, or use it, but because we are deployed on RHEL, customers may be indirectly affected. Customers using RHEL should apply patches provided by Red Hat.

CA Console Management for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI.

CA ControlMinder

CA DataMinder (formerly DLP) products – Software and appliance confirmed not vulnerable. Note: Linux Agents shipped, but no public SSH or Web apps are used in these agents. Customers should patch bash shell on any Linux server with DataMinder agents. DataMinder agents should continue to function normally.

CA Digital Payments SaaS (previously patched)

CA Directory

CA eCommerce SaaS / On Demand (previously patched)

CA Endevor Software Change Manager

CA Federation (formerly SiteMinder Federation)

CA GovernanceMinder

CA IdentityMinder

CA Infrastructure Management

CA JCLCheck

CA Job Management for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI.

CA NetQoS GigaStor Observer Expert

CA Network Flow Analysis

CA Performance Management for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI.

CA RiskMinder

CA Service Desk Manager

CA Service Operations Insight (SOI)

CA SiteMinder

CA SOLVE:Access

CA Spectrum for Linux - Not vulnerable. Be sure to apply bash fixes from your underlying operating system vendor.

CA Strong Authentication

CA System Watchdog for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI.

CA Top Secret

CA Universal Job Management Agent for OpenVMS - Our OpenVMS products do not bundle bash, and they do not supply bash scripts; we use nothing but the native DCL CLI.

CA Virtual Assurance for Infrastructure Managers (VAIM)

Solution

CA Technologies has issued the following fixes to address the vulnerabilities.

CA API Management: Patches for Linux appliance are available through CA Support to customers of Gateway (applicable for all versions – 6.1.5, 6.2, 7.0, 7.1, 8.0, 8.1, 8.1.1, 8.1.02).

CA Application Performance Management: KB article for APM TIM has been published. APM TIM is the only part of APM that was affected. Refer to TEC618037.

CA Application Performance Management Cloud Monitor: New images are available for subscribers. Download the latest OPMS version 8.2.1.5. For assistance, contact CA Support.

CA Customer Experience Manager (CEM) Transaction Impact Monitor (TIM): Very low risk. 9.6 is not affected. 9.5 Installation uses Bash. We do not use Bash at all for the CEM operating system that we have shipped in the past. This means that customers who patch the OS will not impact the ability of the CEM TIMsoft from operating. However prior to version 9.6, the TIM installation script does use the bash shell. See new KB article TEC618037 for additional information.

CA Layer 7 (API Gateway, Mobile Access Gateway, API Management Portal): Fixes for all Bash vulnerabilities and a security bulletin are available on the Layer 7 Support website.

CA User Activity Reporting Module (Enterprise Log Manager): All 12.5 and 12.6 GA versions are potentially affected. Patches provided on 2014-09-30. To get the patch, use the OS update functionality to get the latest R12.6 SP1 subscription update. Note that you can update R12.5 SPx with the R12.6 SP1 OS update. For assistance, contact CA Support.

Workaround

None

To help mitigate the risk, we do strongly encourage all customers to follow patch management best practices, and in particular for operating systems affected by the Bash Shellshock vulnerabilities.
