Linux Distros Unpatched Vulnerability : CVE-2017-2295

high Nessus Plugin ID 221202

Language:

Synopsis

The Linux/Unix host has one or more packages installed with a vulnerability that the vendor indicates will not be patched.

Description

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

 - Versions of Puppet prior to 4.10.1 will deserialize data off the wire (from the agent to the server, in this case) with a attacker-specified format. This could be used to force YAML deserialization in an unsafe manner, which would lead to remote code execution. This change constrains the format of data on the wire to PSON or safely decoded YAML. (CVE-2017-2295)

Note that Nessus relies on the presence of the package as reported by the vendor.

Solution

There is no known solution at this time.
