CVE-2016-3107 & CVE-2016-3108: Safely generate Nodes certificate.

This commit fixes two CVEs.

CVE-2016-3107¶

Install Node certificate with 640, apache owned (CVE-2016-3107).

Prior to this commit, the Node certificate had been installed world-readable:

$ ls -lah /etc/pki/pulp/nodes/ total 4.0K drwxr-xr-x. 2 root root 21 Apr 8 16:37 . drwxr-xr-x. 4 root root 90 Apr 8 16:37 .. -rw-r--r--. 1 root root 3.2K Apr 8 16:37 node.crt

This commit adjusts the generation script to limit the permissions to 0640, and to adjust the group ownership to the apache group.

fixes #1833

CVE-2016-3108¶

Safely create tmp dir for the Nodes certificate (CVE-2016-3108).

Security researcher Sander Bos contacted the Pulp team to notify us that the pulp-gen-nodes-certificate script suffers from the same exploit as was found in CVE-2016-3095, namely that the $TMP directory that contains the Nodes private key was created in an unsafe manner. This commit contains his proposed fix to use mktemp -d to safely create the directory.

Additionally, I added a set -e so that the script would exit upon error.

Thanks to Sander Bos for taking the time to carefully inspect the Pulp codebase and for writing a wonderfully detailed report describing the issue and the fix for it.
