How to patch the Heartbleed bug (CVE-2014-0160) in OpenSSL?

0 0

A major vulnerability was recently patched in OpenSSL. Tableau Server 8.1.5 currently uses a vulnerable version OpenSSL. The patched version of OpenSSL is 1.0.1g. Here's a quick guide on how you can perform an in-place upgrade of OpenSSL to close the security hole. Please do so at your own risk, make backup copies of the files before doing anything, and understand this may invalidate your support while the changes are in place.

This will primarily affect Tableau Server instances utilizing SSL support, but could also affect reverse proxy configurations. It is more important to patch vulnerable servers that are internet facing.

Obtain updated Windows OpenSSL binaries from: Download the package Win32 OpenSSL v1.0.1g Light (or your desired version) to your Tableau Server Run the application, extract to a local folder and be sure to have the installer copy the DLLs to that same local folder Stop Tableau Server Make a backup...

If you have not heard, there is a good bit of news floating about regarding the heartbleed bug. It impacts several versions of OpenSSL. This bug is primarily a server issue and most clients are not impacted directly.

Here is an ubuntu link that discusses this.

Read the area regarding "How do I recover on a client"

If you want to do it on your own, you can go to yourself and get the sources (get the latest 1.0.1g)

If you still want to patch this with some help - read on..(which is not a bad idea in any case). There are some steps to do this. Please read carefully and follow along if you are not comfortable doing this sort of thing.(you have to be connected to the internet)

1. Open a terminal and enter the command 'sudo apt-get install build-essential" and provide admin credentials. This downloads...

The bug is known as Heartbleed.

Am I vulnerable?

Generally, you're affected if you run some server that you generated an SSL key for at some point. Most end-users are not (directly) affected; at least Firefox and Chrome don't use OpenSSL. SSH is not affected. The distribution of Ubuntu packages isn't affected (it relies on GPG signatures).

You are vulnerable if you run any kind of server that uses OpenSSL versions 1.0–1.0.1f. The affected Ubuntu versions are 11.10 oneiric through 14.04 trusty pre-releases. It's an implementation bug, not a flaw in the protocol, so only programs that use the OpenSSL library are affected. If you have a program linked against the old 0.9.x version of OpenSSL, it isn't affected. Only programs that use the OpenSSL library to implement the SSL protocol are affected; programs that use OpenSSL for other things are not affected.

If you ran a vulnerable server exposed to the Internet, consider it compromised unless your logs...

What is the CVE-2014-0160?

CVE-2014-0160 is the official reference to this bug. CVE (Common Vulnerabilities and Exposures) is the Standard for Information Security Vulnerability Names maintained by MITRE. Due to co-incident discovery a duplicate CVE, CVE-2014-0346, which was assigned to us, should not be used, since others independently went public with the CVE-2014-0160 identifier.

Why it is called the Heartbleed Bug?

Bug is in the OpenSSL's implementation of the TLS/DTLS (transport layer security protocols) heartbeat extension (RFC6520). When it is exploited it leads to the leak of memory contents from the server to the client and from the client to the server.

What makes the Heartbleed Bug unique?

Bugs in single software or library come and go and are fixed by new versions. However this bug has left large amount of private keys and other secrets exposed to the Internet. Considering the long exposure, ease of exploitation and...

Heartbleed Bug Summary

A new bug in OpenSSL has been discovered that allows a remote attacker to access parts of memory on systems using vulnerable versions of OpenSSL (eg: HTTPS). This can allow an attacker to gain access to private keys, usernames, passwords and eavesdrop on encrypted traffic. For more information, see:

What versions of OpenSSL are affected?

OpenSSL 1.0.1 to 1.0.1f are affected. The vulnerability is patched in OpenSSL 1.0.1g; Most 6.x systems are vulnerable as they run OpenSSL 1.0.1e (openssl-1.0.1e-16.el6_5.4). If in doubt, check your OpenSSL package version with the following command:

Note: OpenSSL version openssl-1.0.1e-16.el6_5.7 includes the backported fix for this vulnerability.

How can I protect my CentOS system from this vulnerability?

An update has been released that patches this vulnerability in OpenSSL 1.0.1e; special thanks to the RHEL and CentOS team for releasing a patched...

OpenSSL versions 1.0.1 through 1.0.1f contain a flaw in its implementation of the TLS/DTLS heartbeat functionality. This flaw allows an attacker to retrieve private memory of an application that uses the vulnerable OpenSSL library in chunks of 64k at a time. Note that an attacker can repeatedly leverage the vulnerability to retrieve as many 64k chunks of memory as are necessary to retrieve the intended secrets. The sensitive information that may be retrieved using this vulnerability include:

Primary key material (secret keys) Secondary key material (user names and passwords used by vulnerable services) Protected content (sensitive data used by vulnerable services) Collateral (memory addresses and content that can be leveraged to bypass exploit mitigations)

Exploit code is publicly available for this vulnerability. Additional details may be found in CERT/CC Vulnerability Note...

OpenSSL Security Bug - Heartbleed / CVE-2014-0160


The purpose of this document is to list Oracle products that depend on OpenSSL and to document their current status with respect to the OpenSSL versions that were reported as vulnerable to the publicly disclosed ‘heartbleed’ vulnerability CVE-2014-0160.

Specifically, this document will list: (1) Oracle products that never used OpenSSL versions reported to be vulnerable to CVE-2014-0160; (2) Oracle products still under investigation, which may be vulnerable to CVE-2014-0160, (3) Oracle products that are likely vulnerable to CVE-2014-0160 but have fixes available from Oracle, (4) Oracle products that are likely vulnerable to CVE-2014-0160 but for which no fixes are currently available, (5) Products that do not include OpenSSL in their default distribution, (6) Status for Oracle Cloud, (7) Status for My Oracle Support and Oracle Advanced Customer Support Services, and finally (8)...

If there are problems, head to the FAQ

Enter a URL or a hostname to test the server for CVE-2014-0160.

All good, seems fixed or unaffected!

Uh-oh, something went wrong:
Check what it means at the FAQ.
It might mean that the server is safe, we just can't be 100% sure! If you know what you are doing, tick the ignore certificates box. Otherwise please try again!


Here is some data we pulled from the server memory: (we put YELLOW SUBMARINE there, and it should not have come back)

Please take immediate action!

You can specify a port like this 443 by default.

What is OpenSSL?

OpenSSL is a common cryptographic library which provides encryption, specifically SSL/TLS, for popular applications such as Apache (web), MySQL (database), e-mail, virtual private networks (VPNs), and more.

What is “the Heartbleed Bug”?

The Heartbleed Bug is a severe vulnerability in OpenSSL, known formally as “TLS heartbeat read overrun (CVE-2014-0160)“. As of April 07, 2014, a security advisory was released by, along with versions of OpenSSL that fix this vulnerability.

What are the risks?

In short, the risks are many. In most circumstances, this flaw allows an attacker to read the memory of servers running vulnerable versions of OpenSSL. This would allow attackers to impersonate users and services, and provide a means for data theft. For example, the exposed memory could include sensitive information such as private keys. If private keys are leaked, then it is possible that SSL certificates are compromised, and in...

– I think now it’s not a new name for you, as every informational website, Media and Security researchers are talking about probably the biggest Internet vulnerability in recent history. It is a critical bug in the OpenSSL's implementation of the TLS/DTLS heartbeat extension that allows attackers to read portions of the affected server’s memory, potentially revealing users data, that the server did not intend to reveal.

After the story broke online, websites around the world flooded with the heartbleed articles, explaining how it works, how to protect, and exactly what it is. Yet many didn’t get it right. So based on the queries of Internet users, we answered some frequently asked questions about the bug.


Absolutely NO, It's not a virus. As described in our previous
