Package : puppet
Version : 2.7.23-1~deb7u4
CVE ID : CVE-2017-2295
Debian Bug : 863212

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.

For Debian 7 "Wheezy", these problems have been fixed in version
2.7.23-1~deb7u4, by enabling PSON serialization on clients and refusing
non-PSON formats on the server.

We recommend that you upgrade your puppet packages. Make sure you
update all your clients before you update the server otherwise older
clients won't be able to connect to the server.

these updates to your system and frequently asked questions can be
