Description

The pa_drop_root function in PulseAudio 0.9.8, and a certain 0.9.9 build, does not check return values from (1) setresuid, (2) setreuid, (3) setuid, and (4) seteuid calls when attempting to drop privileges, which might allow local users to gain privileges by causing those calls to fail via attacks such as resource exhaustion.

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.
