Debian DLA-1709-1 : waagent security update

medium Nessus Plugin ID 122824

Language:

Synopsis

The remote Debian host is missing a security update.

Description

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.

Solution

Upgrade the affected waagent package.
