Francis McBratney discovered that the Windows Azure Linux Agent created swap files with world-readable permissions, resulting in information disclosure.

For Debian 8 ‘Jessie’, this problem has been fixed in version 2.2.18-3~deb8u2.

We recommend that you upgrade your waagent 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.
