3. Description:

The XML Security Library is a C library based on libxml2 and OpenSSL that
implements the XML Digital Signature and XML Encryption standards.

A flaw was found in the way xmlsec1 handled XML files that contain an XSLT
transformation specification. A specially-crafted XML file could cause
xmlsec1 to create or overwrite an arbitrary file while performing the
verification of a file's digital signature. (CVE-2011-1425)
