Description

When an HTTP/2 stream was destroyed after being handled, the Apache HTTP Server prior to version 2.4.33 could have written a NULL pointer potentially to an already freed memory. The memory pools maintained by the server make this vulnerabilty hard to trigger in usual configurations, the reporter and the team could not reproduce it outside debug builds, so it is classified as low risk.

Solution(s)

  • apache-httpd-upgrade-2_4_33

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.
