Published Aug 6, 2008
·
Updated

Daniel Veillard discovered that a specially crafted document can lead to a recursive evaluation of entities, the result being an exhaustion of memory and CPU usage

Acknowledgements:

Red Hat would like to thank Andreas Solberg for responsibly disclosing this issue.

Other sources

libxml2 2.6.32 and earlier does not properly detect recursion during entity expansion in an attribute value, which allows context-dependent attackers to cause a denial of service (memory and CPU consumption) via a crafted XML document.
