Red Hat Security Advisory 2017-2492-01
Posted Aug 22, 2017
Authored by Red Hat | Site access.redhat.com

Red Hat Security Advisory 2017-2492-01 - XML Security Library is a C library based on LibXML2 and OpenSSL. The library was created with a goal to support major XML security standards "XML Digital Signature" and "XML Encryption". Security Fix: It was discovered xmlsec1's use of libxml2 inadvertently enabled external entity expansion along with validation. An attacker could craft an XML file that would cause xmlsec1 to try and read local files or HTTP/FTP URLs, leading to information disclosure or denial of service.
