"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."
