17 Oct 2014 — parser.c in libxml2 before 2.9.2 does not properly prevent entity expansion even when entity substitution has been disabled, which allows context-dependent attackers to cause a denial of service (CPU consumption) via a crafted XML document containing a large number of nested entity references, a variant of the "billion laughs" attack. parser.c en libxml2 anterior a 2.9.2 no previene debidamente la expansión de entidades incluso cuando la substitución de entidades haya sido deshabilitada, lo que permite a at... • http://kb.juniper.net/InfoCenter/index?page=content&id=JSA10705 • CWE-400: Uncontrolled Resource Consumption •

16 Jul 2013 — libxml2 through 2.9.1 does not properly handle external entities expansion unless an application developer uses the xmlSAX2ResolveEntity or xmlSetExternalEntityLoader function, which allows remote attackers to cause a denial of service (resource consumption), send HTTP requests to intranet servers, or read arbitrary files via a crafted XML document, aka an XML External Entity (XXE) issue.
