CVE-2008-3790

Publication date 27 August 2008

Last updated 24 July 2024

Ubuntu priority

Low

Why this priority?

The REXML module in Ruby 1.8.6 through 1.8.6-p287, 1.8.7 through 1.8.7-p72, and 1.9 allows context-dependent attackers to cause a denial of service (CPU consumption) via an XML document with recursively nested entities, aka an "XML entity explosion."
