Architectures of OpenShift and Cloud Foundry PaaS—in a Nutshell

by April 11, 2014

When I was digging into the architectures of Cloud Foundry and OpenShift for a high-level overview, it became obvious that many of their major components have similar functionality: Routers manage user traffic. Working Nodes are used to stage and run Web applications. Managers are the components that manage and monitor Working Nodes and take care…

CVE-2014-0160 Heartbleed

CVE-2014-0160 Heartbleed
Severity
Critical
Vendor
OpenSSL.org
Versions Affected

1.0.1 through 1.0.1f

Description
The (1) TLS and (2) DTLS implementations in OpenSSL 1.0.1 before 1.0.1g do not properly handle Heartbeat Extension packets, which allows remote attackers to obtain sensitive information from process memory via crafted packets that trigger a buffer over-read, as demonstrated by reading private keys, related to d1_both.c and t1_lib.c, aka the Heartbleed bug.
Affected Pivotal Products and Versions
Severity is critical unless otherwise noted.

vFabric Web Server 5.0.x, 5.1.x, 5.2.x, 5.3.x
vFabric GemFire Native Client 7.0.0.X, 7.0.1.X
Pivotal GemFire Native Client 7.0.2.X

Packaged and Offline Buildpacks

by April 3, 2014

With the recent addition of the cf create-buildpack and cf update-buildpack commands, we’ve been looking into changes to how the Java Buildpack is deployed on Cloud Foundry. There is a move afoot to remove the buildpacks from the DEAs in favor of using those commands (with an automated initial install to preserve user-experience) and an outcome of this was the need to more easily create ‘packaged’ buildpacks. In the process of delivering these packages we also realized that we could also deliver “offline” buildpacks. To understand why “offline” buildpacks are interesting, it helps to understand why the buildpack is designed to look for dependencies on the Internet in the first place.
The buildpack uses a number of dependencies (32 of them by last count).
