When parsing and serializing a crafted XML document, the REXML gem
(including the one bundled with Ruby) can create a wrong XML document
whose structure is different from the original one. The impact of this
issue highly depends on context, but it may lead to a vulnerability in
some programs that are using REXML. The issue is fixed in version 3.2.5
of the REXML gem.

An attacker can crash or execute arbitrary code on the affected server
by providing a maliciously crafted XML or image file.
