There has been a lot of discussion recently in regard to a security vulnerability in a version of OpenSSL, commonly known as the “Heartbleed Bug.”
Heartbleed affects OpenSSL, used by a majority of the web to securely send data.

PlanetLab Europe web services have been updated with the latest, fixed, version of OpenSSL, while nodes don’t expose services affected by the Heartbleed bug.

Slices in PlanetLab use a Linux Fedora based distribution. Currently only Fedora 18 doesn’t provide an official update for OpenSSL, but you can install the latest update by issuing the following command:


yum --releasever=19 install openssl openssl-libs glibc
