CVE-2013-0175 (opens in a new tab)Amendment
The Debian security team deemed this advisory irrelevant for Debian:unstable.
NVD Description
Note: Versions mentioned in the description apply only to the upstream ruby-multi-xml package and not the ruby-multi-xml package as distributed by Debian.
multi_xml gem 0.5.2 for Ruby, as used in Grape before 0.2.6 and possibly other products, does not properly restrict casts of string values, which allows remote attackers to conduct object-injection attacks and execute arbitrary code, or cause a denial of service (memory and CPU consumption) involving nested XML entity references, by leveraging support for (1) YAML type conversion or (2) Symbol type conversion, a similar vulnerability to CVE-2013-0156.
