Vulnerability from gsd
Modified
2018-01-29 00:00
Details
The version of libxml2 packaged with Nokogiri contains a vulnerability. Nokogiri has mitigated these issue by upgrading to libxml 2.9.5. Wei Lei discovered that libxml2 incorrecty handled certain parameter entities. An attacker could use this issue with specially constructed XML data to cause libxml2 to consume resources, leading to a denial of service.
