OSGeo-Live and HeartBleed vulnerability
14 April 2014
As described in many widely available posts on the Internet, the HeartBleed vulnerability is exposed when network software uses the Transport Layer Security (TLS) feature built on top of a current version of the encryption library openssl. The fix to the vulnerability is to upgrade the openssl package via the Ubuntu/Debian apt mechanism.
No software on the OSGeo-Live is configured to serve network connections using TLS "out of the box." However, some software (such as QGis) which provide WMS connectivity to other network services, may create a reverse-vulnerability when a secure connection is established. By patching your OSGeo-Live openssl library, you can close that reverse-exposure.
Please note that the OSGeo-Live project does not recommend using OSGeo-Live "as-is" for production deployment on the Internet.
All users of OSGeo Live from versions 6.0 to the present 7.9 release are strongly encouraged to apply software updates to any installed system.
OSGeo-Live releases affected
OSGeo-Live releases based on Ubuntu 12.04 are affected. This includes versions:
How to Fix
The OSGeo-Live project recommends that all installed versions of an affected OSGeo-Live release follow at a minimum, these steps:
sudo apt-get update sudo apt-get install libssl1.0.0
The default password is "user" (four characters).
Using the graphical update manager will also work, click the 8 pointed star in the top toolbar. Make sure to check for updates and apply any updates to libssl available.
A restart of all services is required after the update is applied, otherwise old libs are used for RAM. You can either restart by hand or reboot the whole system.
