TITLE

libxml2 of xmlreader Denial of service in Japan (DoS) Vulnerability

DESCRIPTION

The xmlreader in libxml allows remote attackers to cause a denial of service (memory consumption) via crafted XML data, related to an XML Entity Expansion (XEE) attack. Libxml2 is prone to a denial-of-service vulnerability. It supports multiple encoding formats, XPath analysis, Well-formed and valid verification, etc. xmlreader is one of the components used to read XML. A security vulnerability exists in libxml's xmlreader component. CVE-ID CVE-2016-1722 : Joshua J. For the oldstable distribution (wheezy), these problems have been fixed in version 2.8.0+dfsg1-7+wheezy5. For the stable distribution (jessie), these problems have been fixed in version 2.9.1+dfsg1-5+deb8u1. For the testing distribution (stretch), these problems have been fixed in version 2.9.3+dfsg1-1 or earlier versions.
