Description

In FreeBSD 12.1-STABLE before r362281, 11.4-STABLE before r362281, and 11.4-RELEASE before p1, long values in the user-controlled PATH environment variable cause posix_spawnp to write beyond the end of the heap allocated stack possibly leading to arbitrary code execution.

Solution(s)

  • freebsd-upgrade-base-11_4-release-p1

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.
