This updated sudo package fixes a potential local root exploit.
Versions of sudo prior to 1.6.4 would not clear the environment before sending an email notification about unauthorized sudo attempts, making it possible for an attacker to supply parameters to the mail program. In the worst case, this could lead to a local root exploit. Users of sudo are advised to upgrade to version 1.6.4, which is not vulnerable to this issue.
With Rapid7 live dashboards, I have a clear view of all the assets on my network, which ones can be exploited, and what I need to do in order to reduce the risk in my environment in real-time. No other tool gives us that kind of value and insight.
