5.0 MEDIUM — AV:N/AC:L/Au:N/C:N/I:N/A:P

Description

The REXML parser in Ruby 1.9.x before 1.9.3 patchlevel 551, 2.0.x before 2.0.0 patchlevel 598, and 2.1.x before 2.1.5 allows remote attackers to cause a denial of service (CPU and memory consumption) a crafted XML document containing an empty string in an entity that is used in a large number of nested entity references, aka an XML Entity Expansion (XEE) attack. NOTE: this vulnerability exists because of an incomplete fix for CVE-2013-1821 and CVE-2014-8080.

Affected configurations

• ruby-lang ruby (<= 1.9.3) • ruby-lang ruby 1.9.3 • ruby-lang ruby 2.0.0 • ruby-lang ruby 2.1.1 • ruby-lang ruby 2.1.2 • ruby-lang ruby 2.1.3 • ruby-lang ruby 2.1.4
