TITLE

libxml2  of  xmlreader  Service operation interruption in  (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. - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Gentoo Linux Security Advisory GLSA 201701-37 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - https://security.gentoo.org/ - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Severity: Normal Title: libxml2: Multiple vulnerabilities Date: January 16, 2017 Bugs: #564776, #566374, #572878, #573820, #577998, #582538, #582540, #583888, #589816, #597112, #597114, #597116 ID: 201701-37 - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - Synopsis ======== Multiple vulnerabilities have been found in libxml2, the worst of which could lead to the execution of arbitrary code.
