It was discovered that there was a potential SSH passphrase disclosure vulnerability in the ansible configuration management system,

The ‘User’ module leaked data that was passed as a parameter to the ssh-keygen(1) utility, thus revealing any credentials in cleartext form in the global process list.

For Debian 8 ‘Jessie’, this issue has been fixed in ansible version 1.7.2+dfsg-2+deb8u1.

We recommend that you upgrade your ansible packages.

NOTE: Tenable Network Security has extracted the preceding description block directly from the DLA security advisory. Tenable has attempted to automatically clean and format it as much as possible without introducing additional issues.
