Description

parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack.

Solution(s)

  • oracle-linux-upgrade-libxml2
  • oracle-linux-upgrade-libxml2-devel
  • oracle-linux-upgrade-libxml2-python
  • oracle-linux-upgrade-libxml2-static

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.
