CVE-2016-9318 – libxml2: XML External Entity vulnerability
https://notcve.org/view.php?id=CVE-2016-9318
libxml2 2.9.4 and earlier, as used in XMLSec 1.2.23 and earlier and other products, does not offer a flag directly indicating that the current document may be read but other files may not be opened, which makes it easier for remote attackers to conduct XML External Entity (XXE) attacks via a crafted document. libxml2 2.9.4 y versiones anteriores, como se usa en XMLSec 1.2.23 y versiones anteriores y otros productos, no ofrece un indicador que indique directamente que el documento actual puede ser leido pero otros archivos no pueden ser abiertos, lo que facilita a atacantes remotos llevar a cabo ataques XML External Entity (XXE) a través de un documento manipulado. • http://www.securityfocus.com/bid/94347 https://bugzilla.gnome.org/show_bug.cgi?id=772726 https://github.com/lsh123/xmlsec/issues/43 https://lists.debian.org/debian-lts-announce/2022/04/msg00004.html https://security.gentoo.org/glsa/201711-01 https://usn.ubuntu.com/3739-1 https://usn.ubuntu.com/3739-2 https://access.redhat.com/security/cve/CVE-2016-9318 https://bugzilla.redhat.com/show_bug.cgi?id=1395609 • CWE-611: Improper Restriction of XML External Entity Reference •
